"If 3D is used well it's a tool for telling a story. If it's only used as a gimmick, which for some films like My Bloody Valentine 3D maybe that's what the audience wants, I think it's less powerful. If it's used to enhance the story and draw the audience into the film, I think it could be the equivalent of what sound or colour was to cinema. There'll be a bunch of bad 3D movies made and the good ones will win out. It'll just take some time. The new system, Real-D, which uses technology invented by a friend of mine, Lenny Lipton, it's great. It's so much better than the 50s version, the anaglyph system with the red and blue lenses. It still has room to improve, it's very dark, but I think the reason we're seeing so many 3D films now is a combination of the emergence of this technology and people always looking for something different -- why would you go to a movie rather than download it or wait for the DVD?"
