question: What cause Warner Bros. to change act 3 of the film "Terminator Slavation"?
article: Terminator Salvation
candidates: McG signed on to direct as the first two films were among his favorites, and he had even cast Robert Patrick (who played the T-1000) in his films. Though he was initially unsure about "flogging a dead horse," he felt the post-apocalyptic setting allowed the film to be different enough so as not to be just an inferior sequel. The idea that events in ' and ' altered the future also allowed them to be flexible with their presentation of the futuristic world. McG met with the series' co-creator James Cameron, and, although he neither blessed nor denigrated the project, Cameron told the new director he had faced a similar challenge when following Ridley Scott's "Alien" with "Aliens". He maintained two elements of the previous films; that John is an outsider to the authorities, and someone of future importance is being protected, and in this film it is Kyle Reese. The first full screenplay for the film was written by "" writers John Brancato and Michael Ferris, who received full screenplay credit. Paul Haggis rewrote Brancato and Ferris's script, and Shawn Ryan made another revision three weeks before filming. Jonathan Nolan also wrote on set, which led to McG characterizing his work on the script as the most important; he chose to contribute to the film after Bale signed on and created Connor's arc of becoming a leader. Anthony E. Zuiker contributed to the script as well. So extensive were the rewrites that Alan Dean Foster decided to rewrite the entire novelization after submitting it to his publisher, because the compiled shooting script was very different from the one he was given beforehand. In the early script drafts, John was a secondary character. Producer James Middleton explained """ was influenced by Jesus Christ, but it was his story. Much in that way, this main character will be influenced by John Connor." The original ending was to have John killed, and his image kept alive by the resistance by grafting his skin onto Marcus' cybernetic body. However, after the ending was leaked on the Internet, Warner Bros. decided to completely change the entire third act of the film. McG and Nolan did continue the Christ element of John's character though, in which he has some followers who believe what he knows about Skynet, and others who do not. McG described the film's theme as "where you draw the line between machines and humans". The friendship between Marcus — who was executed (for murder) when humanity still ruled the world — and Kyle Reese illustrates how war and suffering can bring out the best in people, such as when they worked together to survive during the Blitz. The title was derived from this second chance given to humanity and to Marcus, in addition to John's efforts to save humanity from the machines. The film's original title was "Terminator Salvation: The Future Begins", but this was dropped during filming. Throughout writing, the cast and crew would watch scenes from the three films to pick moments to reference or tribute, including "Come with me if you want to live" and "I'll be back", which is uttered by John in this film. McG found himself having to decide which ideas for references would be included and which would not. An opening scene has John fighting a Terminator on a crashed helicopter, which was storyboarded as a homage to the climax of the original film, where his mother Sarah, having broken her leg, is chased by a crippled Terminator. McG did this to reflect the skills John learned from her.
