It was reported awhile back that Darren Aronofsky walked away for MGM's Robocop reboot. There were claims that he left the project because the studio wanted to shoot the film in 3D and he didn't. I just assumed it was because MGM doesn't have any money to make the movie and Aronofsky wasn't going to wait around for it, and guess what? I was right.
Aronofsky told MTV the following:
The studio is in question, as everyone knows, with ‘The Hobbit’ and all that stuff, and ‘Black Swan’ was ready to go. It just became an easy decision.
All that stuff with the 3-D. I don’t know where that came from. Actually, I do know where that came from. I did one Q&A and someone asked me about 3-D and it was before I saw Cameron’s film and I wasn’t that into it at the time. Someone connected that to ‘Robocop.’ There’s no truth to that story. With the right project, I’m totally into 3-D. Scorsese’s working in 3-D [on 'The Invention of Hugo Cabret']. I am very curious what that’s going to be. Like everyone, I thought ‘Avatar’ was an incredible experience. I’m also interested in what someone like John Waters would do in 3-D. That’s when it starts to become interesting, when you start to see it used in very interesting, different ways. There is a backlash at this point, and I think that’s just because it’s been overexposed, but that’s just because people are rushing to bank in on it. There’s no doubt that interesting things are going to be done in 3-D.
