She had a doctorate in applied physics , specializing in advanced weapon ry . Early life . Carol Marcus was born to and a mother with the maiden name Wallace . Sometime prior to 2259 , she joined Starfleet . Starfleet career . Science officer aboard the USS " Enterprise " . Going after " John Harrison " . When Captain set off for Qo ' noS to find the traitor John Harrison , Marcus boarded his shuttle under the alias Carol Wallace , using her mother ' s maiden name and claiming Admiral Marcus had assigned her to the " Enterprise " . deemed her credentials impressive but decided she was redundant , as he himself had been reinstated as first officer of the , while Kirk welcomed her aboard . Spock confronted Carol about her name not being in the ship ' s records , but before she could explain herself to him , the ship ' s warp core malfunctioned . Spock later revealed her true identity to Kirk . Carol apologized to Kirk for the deception after Harrison was arrest ed , explaining she had used her mother ' s maiden name to board the ship and examine a series of seventy - two experiment al , advanced long - range torpedo s aboard the vessel because she had discovered they had disappeared from all official records after her father had withheld information on them from her . Her father had given the photon torpedo s to Kirk , to fire on Harrison . Marcus went with to examine one of the torpedo s on a deserted planetoid , after Harrison suggested to Kirk that he open one . McCoy accidentally activated the torpedo and trapped his hand , but despite Kirk ordering that she be beam ed up , Carol managed to deactivate the torpedo before the emergency beam - up became necessary . Opening up the dormant torpedo , she and McCoy discovered a cryogenically frozen man inside . When questioned , Harrison revealed that he was Khan Noonien Singh , that he had been revived to help prepare for war with the Klingon Empire , and that he had planned to smuggle his fellow Augment s in the torpedoes before he was caught . Admiral Alexander Marcus arrived in the , a warship designed by Khan , and began firing on the " Enterprise " . Carol Marcus revealed her presence to him in an effort to persuade her father to cease the attack , but Alexander simply beamed her over and carried on . When taken to the bridge , Carol smacked her father , telling him she was ashamed to be his daughter . But he ignored her , believing the cover - up was necessary . Scotty deactivated the " Vengeance " s weaponry , giving Kirk and Khan time to fly to the ship and commandeer it . When they arrived on the bridge , Scotty shot to stun Khan while Kirk admonished the admiral for compromising Starfleet . Kirk ordered the admiral out of his command chair , citing that while he could force him out , he preferred not to do it in front of Carol . However , one stun shot was ineffective to keep Khan down , and he promptly beat Scott and Kirk . He then turned to Admiral Marcus , who tried to flee into a turbolift . Carol tried to stop and reason with him , but he responded by breaking her leg . Then he grabbed her father and crushed his skull before her very eye s , and she responded by screaming in horror . Along with Kirk and Scott , Carol was then beamed , by Khan , into the " Enterprise " s brig . Kirk brought her to sickbay for McCoy to patch her up . Khan resumed bombarding the " Enterprise " , and the damage caused the ship to fall to Earth . Kirk went into the warp core and reactivated the engines , preventing the " Enterprise " from crashing , but at the cost of poisoning himself . Marcus watched as Kirk ' s unconscious body was brought to sickbay . However , McCoy realized Khan ' s blood could be used to heal him . He and Marcus placed Kirk in one of the Augments ' cryotubes to put him in suspended animation . Spock and beamed down to apprehend Khan , after he crashed the " Vengeance " into San Francisco , and the blood transfusion proved successful . The five - year mission . Carol attended a memorial service for those killed by Khan and her father , close to a year later .

" " Appendices . Background information . The alternate - reality Carol Marcus was played by Alice Eve . Origins . A young Carol Marcus was in an early script draft of the film . She would have been represented as meeting Kirk during his adolescence and living near him . Co - writer Roberto Orci explained , " " We wanted to potentially lay down the foundation for their friendship [ . . . ] And then literally because of the nature of the introductory story and making sure that our core group of characters had the proper amount of story that they deserve , she went into the potential future draft . " " Introducing Carol Marcus in brought some major implications to the movie , the prime - universe representation of the character having made a singular appearance – as the mother of Kirk ' s son , David Marcus , and a scientist involved in testing the Genesis Device – in . " " What we didn ' t want to do was rush it in a way that felt too familiar and too predictable , " " commented Alex Kurtzman , regarding how he and the other screenwriters wrote the role into " Star Trek Into Darkness " . " " The idea with Carol was introduce a character that implies a lot of things , but leave it open enough that anything could happen in the next movie . " " Showing Carol Marcus changing into her flightsuit , in " Star Trek Into Darkness " , was motivated by Director J . J . Abrams wanting to appeal to " Star Trek " s male fan base , which is fairly large . That the film would show Dr . Marcus in her underwear was heavily discussed during many story conversations between the screenwriters , as they contemplated how they were going to justify that . Originally , Kirk would have stumbled on Marcus changing as she prepared to open the torpedo in space , but budgetary limitations prevented the writers from setting the disarming scene in space ; Orci acknowledged that having her consequently change into a flightsuit was not as necessary as showing her change into a spacesuit . The writers approached the subject from the point of view that , like in " Star Trek II " , Carol Marcus was again to be represented as bold in her interactions with Kirk , despite each of them being another form of their character than from " The Wrath of Khan " . " " We figured , how do we harness the spirit of that in this scene , " " recalled Alex Kurtzman , " " and that ' s ultimately where we came to it from [ . . . ] It ' s not something we went into blindly , and certainly we all sat in a room going , okay , we ' re going to be criticized for this , but how do we justify this in a way that feels like it was thought about ? " " In a Yellow Revision of the screenplay for " Star Trek Into Darkness " , Carol Marcus , upon being introduced in the script , was described as wearing " Starfleet blues . " Also , a line of dialogue characterized her as holding " advanced doctorates in applied physics , " although this was later changed to instead describe her as having a singular doctorate in that subject . ( " The Voyage Begins . . . Again ! " , " Featurettes " , " " Blu - ray special features ) In the same draft of the screenplay , Carol Marcus used the alias " Caroline Wallace " . ( " The Voyage Begins . . . Again ! " , " Featurettes " , " " Blu - ray special features ) Both this and the alias she ultimately uses in the movie , " Carol Wallace " – besides referring to her mother ' s name – are likely in tribute to Janet Wallace . That role was originally written as Kirk ' s love interest in early drafts of " The Wrath of Khan " and evolved into Carol Marcus in later drafts of the same film . ( " " ; ) Both women were envisioned as strong - willed , intelligent scientists with whom Kirk had previously been emotionally involved . Scotty actor Simon Pegg was thrilled to discover that Carol Marcus is involved in " Star Trek Into Darkness " . " " Looking at it from the outside , " " Pegg recalled , " " when I first saw her name in the script , it was exciting , ' cause Carol Marcus is a figure from " Star Trek " history . " " Kirk actor Chris Pine once referred to the character , as written for " Into Darkness " , as " a really interesting part . " ( , issue 80 , p . 23 ) Casting the role . It was the people involved in making " Star Trek Into Darkness " that drew Alice Eve to it , rather than any familiarity with " Star Trek " , which she didn ' t know much about before taking the role of Carol Marcus . " " I didn ' t know who Carol Marcus was , " " she admitted . Alice Eve was likewise unaware , when she auditioned for the part , that it was the role of Carol Marcus she was trying out for . Although no full script was yet available , J . J . Abrams sent some scenes to her . Before Eve received the scenes , Abrams asked that she prepare them . ( ) " " I got a few pages of this character ' s scenes and a scene that was kind of imagined , that wasn ' t in the movie , " " remembered Eve . " " It was just so well constructed and so well imagined and so truthful that I wanted to be part of this group of people that told stories in that way . " " The audition scene that is not in the movie was , in Eve ' s words , " an extended dialogue scene " between Carol Marcus and her father . The scene ( whose plot points were included elsewhere in the film ) was helpful to Eve in her understanding of Carol Marcus . In fact , despite not knowing the name of the character she was auditioning to play , Eve got a distinct impression of the role from the collection of scenes , later stating , " " I got a sense [ that ] [ . . . ] the journey of the character [ J . J . ] wanted was a girl who was struggling with her relationship with her father . " " Eve also consistently assumed that it was an already established character she would be playing , rather than a brand new one . Alice Eve proceeded to do as J . J . Abrams had requested by preparing the scenes . " " I did that , and met with him , where we work - shopped the material , " " said Eve . This meeting was the first encounter between them , Eve having never auditioned for Abrams before nor even crossed paths with him . " " The process of working with him was incredibly rewarding for me , and enjoyable , " " Eve continued . " " Then I spoke to him and his producing partner , Bryan Burk , afterwards . " " ( ) Alex Kurtzman was another production staffer who witnessed the audition . He later recollected , " " When we started auditioning Carol , in walked Alice , who was so wonderful and had this kind of lovely quality and brightness and intelligence . That inspired us to think about , ' OK , if we like Alice , then how are we going to craft the character around the actress that we like and make it familiar and not inconsistent with what you ' ve seen before ? " " Although it was by now obvious to Eve that the project she was auditioning for was " Star Trek " , Abrams didn ' t inform her that the character she was being considered for was Carol Marcus . " " To be honest , that didn ' t mean anything to me anyway , " " Eve conceded , " " because I wasn ' t overly familiar with the universe . He gave me a sense of who the woman was , what drove her , and what her motivations were . All of that gave me enough to create a sketch . " " ( ) About ten days after Alice Eve ' s initial meeting with J . J . Abrams , he called her and asked her to do the forthcoming film . ( ) The news that Eve was cast in the part extremely excited Simon Pegg . " " I think I maybe got the job because I naturally speak very fast , " " reckoned Eve ; she implied that the quickness of her speaking worked well in sync with Abrams ' thinking , observing that he thinks " very fast . " ( , Issue 287 , p . 92 ) Initial movie depiction . As Alice Eve naturally has an English accent ( though can do a considerably convincing American one ) whereas the original portrayal of Carol Marcus featured an American accent , there was " ample discussion , " said Eve , as to which accent Marcus was to have in " Star Trek Into Darkness " . Ultimately , the Oxford - educated Eve was allowed to portray the character with her own accent , later quipping , " " The association sometimes is that English people are more intelligent than Americans . Of course , it isn ' t true , but I think we decided to play into that stereotype . . . because she is such a super - brain . " " Once Alice Eve found out which character she had been selected to depict , Eve was happy to have been cast as Carol Marcus . This was because the vast differences between how she had been written in " Star Trek Into Darkness " and her previous presentment meant that Eve didn ' t have to copy that earlier portrayal . Nevertheless preparing for the role by watching every episode of first season and , Eve took certain cues from the prime - universe version of Dr . Marcus , saying , " " Oh , it ' s information you have to carry , definitely . It doesn ' t shape it , but it will maybe inform certain choices . " " Eve kept in mind that Marcus was originally depicted as being " cleverer than Kirk . " The actress noted that she thus kept Marcus ' " composure and her conviction and her thoughts , her belief in her intellect . " However , believing that the prime - universe Carol Marcus has " great composure " – brought about by age as well as by lost aspirations and relationships – Eve found that she had to temper this characteristic to play a younger , less experienced rendition of the character . " " This Carol Marcus that I was playing , I didn ' t feel she was tough , " " offered Eve . " " I wanted to bring a vulnerability to her , because she was at the beginning of her journey as a woman [ . . . ] I wanted to bring that sense of hope and softness to her , along with the list of capabilities that are on the page . And she became mine at some point , I understood that there was a tradition , but I didn ' t hold too tightly to any of it because she was mine now . " " ( ) Having spent much of her early twenties in further education , Alice Eve found she could relate to the highly educated Carol Marcus . " " I was familiar with that kind of mind , " " Eve noted . " " I think she has a specific motivation that was one that I understood and could sympathize with , so both resonated with me quite strongly . " " ( ) Eve wasn ' t entirely like the character , though . " " I definitely knew that Carol was braver than I was when we started , " " Eve stated , " " and more tenacious . " " ( ) Hair Department Head Mary L . Mastro was conscious of styling Alice Eve ' s hair , for her role as Carol Marcus , in such a way as to be similar to that of the character ' s initial representation . " " Alice doesn ' t look anything like the person who originally played that role , " " observed Mastro , " " but we wanted to give her a sensibility that was similar , yet not have it be that period . " " The hairstyle for the revised Carol Marcus was also influenced by a lengthy debate about the nature of hair in the future time period of " Star Trek " and the outcome of this discussion : the realization that J . J . Abrams usually tended toward stylistic minimalism in " Star Trek " . " " So we used the famous Vidal Sassoon bob from the ' 60s to build a hairstyle , " " explained Alice Eve . " " We think it showed a sense of youth , and was in keeping with the original imagery of the ' 60s show , but we modernized it and it added a clean efficiency to the line . It was that stuff we ended up falling back on , and J . J . was involved in all aspects . He was even involved with the color I chose to wear on my nails . " " ( ) Alice Eve found that portraying the sexual chemistry between Dr . Marcus and Captain Kirk came naturally to herself and Chris Pine , mainly due to him having blue eyes that she found " really beautiful . " The actress also appreciated that , while Marcus took " great " support from her relationship with Kirk , their bond didn ' t define Marcus and that she " was a very determined woman in her own right , dealing with her own struggles . " Performing the scene wherein Carol Marcus briefly appears in her underwear was fairly straightforward . When asked whether she found portraying the scene awkward , Alice Eve replied , " " That ' s always an experience . I enjoyed working with everyone very much , I felt very comfortable in that environment and we ' d all been training incredibly hard to , like , look like we were capable of living in space and saving the world . So , you know , I enjoyed the whole process of making that film , it was a good one . " " The image of Marcus wearing only her underwear circulated around the Internet . There are mixed opinions about the scene , one criticism being that it undermined Marcus as a character . Despite the brief shot turning out to be controversial and criticized by some as an exploitative and unnecessary sexualizing of an otherwise strong female character , Eve feels it was neither overly sexualizing her persona in the film nor inappropriate , given that Kirk is shown having sex with women and with his shirt off in both " Star Trek " and " Star Trek Into Darkness " . Eve has argued that not only was she fit when she filmed the scene but also that exhibiting the beauty of the female body in a strong character does not detract from such a character ' s strength or power . In addition to being highlighted in a deleted scene from " Star Trek Into Darkness " which explains the split universe ' s Carol was raised by her mother in England and thereby accounts for her British accent , Editors Mary Jo Markey and Maryann Brandon revealed that Kirk ' s original first meeting with Carol , after Pike ' s death , was also cut from the film and replaced during additional photography , which they felt added to Spock ' s , and the audience ' s , initial suspiciousness about her . ( " Star Trek Into Darkness " iTunes enhanced commentary ) Aftermath of first film appearance . Alice Eve has expressed happiness with her initial movie appearance as Carol Marcus , saying , " " I really enjoyed the character I got to play . " " Following the shooting of " Star Trek Into Darkness " , the actress clarified , " " I know that I admire her tenacity , and her bravery . It ' s always great to play someone you can learn from [ . . . ] I hope I ' ve learned from her . " " ( ) Eve has also expressed happiness that the alternate reality take on the character has been intriguing for online fans . " " It ' s good to know that people are interested in Carol Marcus , " " she said . " " I was really glad to be able to play her , with her intelligence and her quick wit with Kirk . " " ( " The A - Z of Star Trek " , " SFX " Special Edition 61 , p . 63 ) Eve also requested that there be an action figure showing herself as Dr . Marcus , remarking , " " I would like one . " " Alice Eve has stated that , should she return as Carol Marcus in another film after " Star Trek Into Darkness " , she would " like to see Carol take the ( captain ' s ) chair for at least an hour . " The actress has been noncommittal about the story points relating to Marcus ' relationship to Kirk , observing that the alternate reality leaves it open as to whether they eventually have a child , as in the prime universe . " " I ' d love any eventuality with Carol , " " Eve commented . " " I love playing her . I love her strength and independence of mind . So I ' d like to continue to see that . " " However , Carol Marcus and her relationship with Kirk intentionally weren ' t included in the next film , . " " There were many iterations where we did go and explore [ Carol Marcus ] , but we figured it was two and a half years [ after " Into Darkness " ] … It was something we talked about and worked on , but in the presentation of this film it didn ' t quite fit in . It ' s there with the transporter and everything , " " laughed " Star Trek Beyond " Director Justin Lin . Simon Pegg , who co - wrote the film , has likewise stated that Carol ' s absence was explained in one of the initial drafts . Originally , she was said to have gone off to start early research work on the Genesis project . Apocrypha .
