Question: Orci was born in Mexico City on July 20, 1973, to a Mexican father and a Cuban mother. His mother immigrated to the United States with her parents after Fidel Castro came to power. Orci grew up in Mexico, and moved with his family to the United States at the age of 10. He was raised in Texas, Los Angeles and Canada.

Orci and Kurtzman began their writing collaboration on the television series Hercules: The Legendary Journeys, after being hired by Sam Raimi. After actor Kevin Sorbo suffered a stroke, the duo were required to come up with inventive ideas to minimize his appearances on screen. Due to this work, they became show runners at the age of 24. They were also involved in the sister-series to Hercules, Xena: Warrior Princess. They sought to move to writing for a network-based television series, but found this difficult. After receiving a series of negative responses, they met with J. J. Abrams who was starting work on Alias at the time. The meeting went well, and resulted in them working on the series. They would go on to work together again on the Fox science fiction series Fringe where all three were listed as co-creators. Orci and Kurtzman received their break in writing for films in 2004, with the Michael Bay film The Island, for which they developed the spec script by Caspian Tredwell-Owen. When Kurtzman and Orci first met Bay, he asked the pair "Why should I trust you?", to which Orci replied "You shouldn't yet. Let's see what happens." While the film was not an overwhelming success, they were brought back for Bay's following film, Transformers, after producer Steven Spielberg asked them to come in for a meeting. The movie took in $710 million at the box office. Following their work on that film, the duo were brought in to revise the script for Zack Snyder's Watchmen, in an uncredited capacity. They worked once more with Abrams, on Mission: Impossible III. When they collaborated once more with Bay for Transformers: Revenge of the Fallen, they were under significant time pressures due to the 2007-08 Writers Guild of America strike. Kurtzman and Orci had two weeks to outline the film, and after the strike Bay had them moved into the Hotel Casa del Mar. The hotel was six blocks away from his office, enabling Bay to conduct surprise inspections. In the period between 2005 and 2011, the films written by Kurtzman and Orci grossed more than $3 billion, leading to Forbes describing them as "Hollywood's secret weapons". The busyness of their screenwriting careers required them to collaborate with other writers due to the number of projects they were involved in. For example, on Transformers: Revenge of the Fallen, they teamed up with Ehren Kruger, who took over from them on the writing duties for the Transfomers franchise from Transformers: Dark of the Moon onwards.

Question: Yoko Ono (born February 18, 1933) is a Japanese multimedia artist, singer, songwriter, and peace activist who is also known for her work in performance art and filmmaking. She performs in both English and Japanese. She is known for being the second wife and widow of singer-songwriter John Lennon of the Beatles. Ono grew up in Tokyo and also spent several formative years in New York City.

During the last two years that the Beatles performed, Lennon and Ono created and attended their own public protests against the Vietnam War. On March 20, 1969, they were married at the registry office in Gibraltar and spent their honeymoon in Amsterdam, campaigning with a week-long Bed-In for Peace. They planned another Bed-In in the US, but were denied entry to the country. They held one instead at the Queen Elizabeth Hotel in Montreal, where they recorded "Give Peace a Chance". Lennon later stated his regrets about feeling "guilty enough to give McCartney credit as co-writer on my first independent single instead of giving it to Yoko, who had actually written it with me." The famous couple often combined advocacy with performance art, such as in "bagism", first introduced during a Vienna press conference, where they satirised prejudice and stereotyping by wearing a bag over their entire bodies. Lennon detailed this period in the Beatles' song "The Ballad of John and Yoko". Lennon changed his name by deed poll on April 22, 1969, switching out Winston for Ono as a middle name. Although he used the name John Ono Lennon thereafter, official documents referred to him as John Winston Ono Lennon, since he was not permitted to revoke a name given at birth. The couple settled at Tittenhurst Park at Sunninghill, Berkshire, in southeast England. When Ono was injured in a car accident, Lennon arranged for a king-sized bed to be brought to the recording studio as he worked on the Beatles' last recorded album, Abbey Road. The two artists collaborated on many albums, beginning in 1968 when Lennon was still a Beatle, with Unfinished Music No.1: Two Virgins, an album of experimental musique concrete. The same year, the couple contributed an experimental piece to The White Album called "Revolution 9". Also on The White Album, Ono contributed backing vocals on "Birthday", and one line of lead vocals on "The Continuing Story of Bungalow Bill." The latter marked the only occasion in a Beatles recording in which a woman sings lead vocals.
