Production Development The show was officially renewed by Fox for a fourth season on May 10, 2017. Just like the second and third seasons, the fourth season also carried a new subtitle for the first half of the season : A Dark Knight. Writing The producers revealed that the season would be based on the comic book stories Batman : The Long Halloween and Batman : Year One. According to executive producer John Stephens, the season would not consist of `` direct adaptations '', but `` loose interpretations '' of the comic book series. Ben McKenzie explained that the structure for the season would be `` the beginning is more Long Halloween, our version of that, and the end is more Year One. '' According to Stephens, the show will handle a horror - oriented direction on the season : `` At the very beginning of the season, Penguin has solidified his control upon Gotham like never before. Where he 's kind of unionized crime. And Scarecrow comes in to basically reintroduce fear into Gotham and to remind people that the dark is still scary out there. And we 're really going to fashion, especially Episode 2, almost a horror movie episode where we really get to see Scarecrow. I think he 's like purely terrifying. Imagine, rather than the other versions of Scarecrow out there -- because there are a lot of different versions -- what if you just really tell Scarecrow as a horror movie ? Because he could be scary as hell. '' Executive producer Danny Cannon stated, `` When the studio asks you to tone back because it 's too scary, you know you 've done something right ! '' Regarding Bruce 's beginning of vigilantism, McKenzie explained that `` We are definitely leaning into Bruce, having learned some of the skills to be a vigilante, now actually attempting it. Now, we have a long, long way to go before he can realistically be Batman, so there will be many stumbles and falls -- and regressions back to being a kid at times -- but Gordon will eventually become aware of what he 's doing and that will bring them against each other. '' David Mazouz also added, `` Bruce really is taking on this vigilante persona and all the things that go along with that. Whether it be creating another persona, a public persona, that 's also definitely going to be a major part of Bruce 's journey this year. His relationship as this other person. Batman is coming. Absolutely. '' Mazouz also stated that he was worried the writers could pull back some aspects from Batman, deeming it `` too fast '' but he was glad it did n't stop. He said that Bruce would take the `` Batman persona '' this season. Cannon also explained that Bruce will be seen `` as the emerging threat he is. '' Alexander Siddig stated that his character will seek to make Bruce his heir and will `` do anything he can to get his hands on him, to manipulate him into what ( Ra 's ) wants him to be. '' He also claimed that the season is `` a season so far of extremes. '' Talking about his character, McKenzie stated, `` Comparatively, perhaps he 's in a better place than some of these other truly evil, evil people. '' But as the season will be with him dealing with Cobblepot, Gordon `` does n't have a lot of good options. He has to either fight him directly or find allies to fight Penguin -- surrogates to fight Penguin -- which leads him down a dark path. So, that 's kind of the way we start for him in season 4. '' According to Stephens, `` We 're going to see Jim make, in some ways, big steps toward I guess what you would call the commissionership. But also we 're going to see Jim, in his quest to save the city, cross different ethical lines than he ever did before. It 's going to bring him to an ethical nadir that we have n't seen him at, and it 's going to be told through the context of a relationship that he has with Sofia Falcone, the daughter of Don Falcone, who 's played by Crystal Reed this year. And that 's going to be a really compelling and interesting relationship. '' Sean Pertwee also stated that the season will also explore Alfred 's mysterious past `` indirectly ''. McKenzie made his writing debut on the episode `` The Demon 's Head '', after previously directing the third season episode `` These Delicate and Dark Obsessions ''. McKenzie went to Los Angeles to work on the writers ' room to break the story and then go back to New York City and finish many drafts. He explained, `` I 've been fiddling around with writing for a long time, but I 'd never written an episode of television, so it was quite a learning process. '' He also added that, `` From being on a set, the directing came fairly naturally. It was challenging, but there were a lot of things that I understood about directing just from observing, just from watching director 's work. Writing often takes place behind - the - scenes. Physical production is not privy to how scripts come out... I was n't so familiar with that process of breaking a story, of starting with a story document, then an outline, and then a draft ; it was informative ''. For the second half of the season, Cameron Monaghan stated that `` We 're borrowing very heavily from some of the most iconic Batman storylines. I think that they 're deep enough, and they show where its really splitting that duality and start totally embracing the main arcs. I think that we did a little bit in season three to bring it into The Killing Joke. '' He also added that the plan for the final episodes is to adapt Batman : No Man 's Land, stating, `` We 're really getting into it this year. I think the way that the story escalates is something that shifts and is not anything the show has done before. I think it 's going to be a really unique experience. Especially by the past few episodes, it 's going to be really... it 's pretty insane. '' Casting Michael Cerveris made his debut in the show in a multi-episode arc as Lazlo Valentin / Professor Pyg. The season also marks Pyg 's first live - action portrayal. With the exception of Benedict Samuel and Michael Chiklis, all main actors from the previous season returned for the show, with Maggie Geha being downgraded to guest star. Crystal Reed joined the series in July 2017 in the series regular role of Sofia Falcone. Alexander Siddig was promoted to the main cast. In September 2017, Michael Cerveris joined the show as Lazlo Valentin / Professor Pyg, in a multi-episode role. Cerveris stated, `` Professor Pyg is a brilliant and chameleon - like person who has a highly developed sense of what 's right and wrong -- it just might not be a sense of right and wrong that corresponds with everybody else 's. '' He also added that, `` When they ( the writers ) had somebody who played Sweeney Todd, they knew the direction they wanted to go... ( Broadway fans who do n't watch Gotham ) might give it a look simply because of that, and find that they have a new favorite show. '' Regarding the Dollotrons, Cerveris stated, `` You know how much he 's liked the Pyg in the comics, but I would say that his focus in Gotham is more on things to do with Gotham and with the city and with Jim Gordon. He 's certainly is the manipulative character, and certainly, you know, is trying to get people to do stuff whether they know why they 're doing it or not. But, that 's sort of exclusive. His whole reason for existing is not the Dollotrons. '' He described the character as having `` a Hannibal Lecter - ish quality. '' He also jokingly added that he could n't eat bacon `` because I just ca n't bring myself to eat my little friends. '' Donal Logue stated, `` We have Michael Cerveris coming in and playing Professor Pyg and he 's such an incredibly gifted actor and, as happens a lot, the gentlest and most gifted of artistic souls can play the darkest, creepiest human beings known to literature or film. '' Besides, the character of Tommy Elliot is set to return to the show, having appeared in the episode `` The Mask ''. However, co-executive producer Bryan Wynbrandt added, `` Obviously when Tommy Elliot is discussed, there 's always is that Hush storyline. That is something that we 've discussed. Right now, we 're kind of still feeling that out. It could be something on the horizon, but I ca n't say for sure. '' Also, Peyton List was cast as a new iteration of Ivy Pepper. According to Bryan Wynbrandt, `` The change was all based on the idea that she 's continuing to evolve to become more of the Ivy from the comic books and what we really enjoyed. In this third evolution you 're going to see a really self possessed, really scary and driven version of the Ivy character, who is intent on kind of making the world in the image she sees it should be, which is the green world. The world where the plants rule and people are an after thought. '' As a concept McKenzie wished to explore, the fourth season is set to bring back the actor Charlie Tahan as Jonathan Crane / Scarecrow, who portrayed the character on the first - season episodes : `` The Fearsome Dr. Crane '' and `` The Scarecrow ''. A trailer was screened on the 2017 San Diego Comic - Con that showed Crane donning a new costume under the Scarecrow persona. McKenzie explained : `` So we met his father Dr Crane in Season 1. So we 've taken our time ; we 're gon na come back now to his son. You know, in circumstances probably not best described now, his son takes on his father 's mantle and becomes the fully - realized Scarecrow. It 's great. We 're able to use this sort of fear toxin that Scarecrow is able to summon. We 're completely unafraid -- or perhaps afraid but we still persist -- in expanding the universe and our capabilities. '' Tahan commented on his character, `` He 's sort of trying to build an army with this toxin. Scarecrow might start brainwashing people. I 'm not exactly sure what his endgame is -- I do n't even know if he knows. He has this revelation that he does n't have to fear fear. '' However, due to Tahan 's commitment to the series Ozark, the role ended up recast with David W. Thompson, who is expected to portray him in the second half of the season. When asked about Jerome Valeska 's return in the season, Stephens stated, `` What I will say about Jerome is that Jerome is in Arkham right now, and when you think about Arkham 's record of keeping people locked up, we will probably see him again before the end of the year. '' In September 2017, Stephens explained, `` You 're totally gon na see him this year. You 're gon na see him in a new position this year '', also teasing that Jerome would be an ally to Penguin on the season. Ben McKenzie said, `` Jerome is one of our most beloved characters. The idea here was to really give the audience more time to enjoy and savor ( Cameron Monaghan 's ) performance. '' Regarding the partnership between Jerome and Penguin, Robin Lord Taylor said `` You have Jerome, who is chaos, and you have Oswald, who is control. So you can imagine, there are ways that those can integrate, but at the same time they 're opposites. '' Stephens also added that Fish Mooney is `` gone for good '', saying, `` Now, that one was it. At a certain point, you got ta say ' Definitely. ' People die at a certain point, and that 's the second or third time they die ( on Gotham ) '' Filming Filming for the season began on June 20, 2017, at Steiner Studios in Brooklyn, New York. In January 2018, it was announced that Ben McKenzie would direct an episode after making his directional debut the previous season. It was later revealed that he would be directing the 16th episode, titled `` One of My Three Soups ''. Production on the season officially wrapped in late March 2018. Release Broadcast The season was originally set to air on September 28, 2017, on Fox in the United States. However, on July 28, 2017, Fox decided to move up the premiere to September 21, 2017 in order to give its companion newcomer series The Orville a continuous run. The fourth season is moving to a Thursday timeslot, alongside The Orville, after airing its past seasons on Mondays. Marketing In July 2017, the cast and crew attended San Diego Comic - Con to discuss and promote the season, showing a five - minute sizzle reel from season 3 as well as the debut trailer for the season. The second episode `` The Fear Reaper '' was screened on September 23, 2017, when Cannon, McKenzie, Taylor, Bicondova, Mazouz, Pertwee and Lucas promoted the series at the inaugural Tribeca TV Festival. Besides, the cast will attend the New York Comic Con on October 2017 to promote the season as well as a Q&A presentation with the cast. The season was also heavily marketed by trailers showcasing Bruce 's beginning of vigilantism as well as Jonathan Crane 's debut, both of whom received positive response from audience with Digital Spy 's Justin Hart commenting, `` Sounds like a perfect time for young Bruce Wayne to finally embrace his destiny as a masked vigilante, does n't it ? '' while Albert Achar from IndieWire commented, `` it looks like it is going to be a very wild ride. '' As part of promotion for the ninth episode `` Let Them Eat Pie '', Fox released a `` red band '' trailer featuring Michael Cerveris as Professor Pyg, teasing a Sweeney Todd storyline in the episode as well as a musical number, which was considered by TV Guide as `` insane.
