Changes from French film
Haggis made a number of key changes from the French film:
They made it quite clear from the beginning of the film, she was innocent, and that he was loving, and he'd do anything to get her out, and, in the end, they lived happily ever after. The bumps along the way were good but I thought I could make him pay a larger price. So, the first thing I did was ask myself what the question was. I need to have a question if I'm starting a movie. The question I came up with, and I'm not sure if it's reflected in the film or not, but it's what I was writing toward, was: Would you save the woman you loved if you knew that by doing so you'd become someone she'd no longer love? That interested me. And that wasn't in the French film at all. The whole issue of innocence was fascinating to me because I didn't necessarily want to say whether she was guilty or innocent. I just wanted John to be the only one who believes she's innocent. The evidence is overwhelming. Even his parents think she's probably guilty. Even their own lawyer. Yet he still believed ... and what that level of belief does for someone, how infectious it is. So, those are two things I was playing with.
Cavayé told The Age regarding the remake of the film by Haggis, he is eager "to be a spectator of my own film". The director commented on the news his film would be remade by Haggis, "It's a strange feeling. I wrote this story in my very small apartment in Paris. When I saw my name next to Russell Crowe on the net, it was amazing."
Haggis based the lead character on himself:
I just sat down and said, "If I had to break the woman I love out of prison, how would I do it?" I'd go on the Internet, that's the first thing I do. I'd Google "How to break out of prison." So, that's exactly what I did. I went on and Googled "How to break out of prison," "How to break into a car," and found these fascinating things, and I just used them. I figured that's what he would do. I also knew I would fail spectacularly, at least at first. But then I would continue. And I'd get the shit beat out of me, and I would trust the wrong people, and I would do the wrong things. I'd start to feel really good about myself, that I'd figured the whole thing out, and then something would go wrong. I would just keep going until I either was caught or we got out or something happened. That's what he does. So, I just tried to make him an everyman. I loved the fact that this guy was also an English teacher, so he was a romantic. He was talking about Don Quixote. He's got this whole romanticized vision of how you sacrifice yourself for a woman, how you go about something like this. It's terribly romanticized and so completely impractical.Haggis also based John's research of prison break-out techniques on his own Internet research on the Church of Scientology after its San Diego chapter endorsed 2008 California Proposition 8, which revealed the faith's controversies to him and led to him leaving the church.
