Scott Derrickson and C. Robert Cargill, respective director and co-writer of the upcoming Deus Ex movie, discuss plans to adapt the action/RPG series for the silver screen with CraveOnline. Here's a bit from Cargill answering how they plan to avoid the obvious trap that "basically every video game movie has sucked before." He replies:

Yeah. Yeah, the chief philosophy is we’re not making a video game movie, we’re making a cyberpunk movie. We’ve taken a look at what’s worked in video games and what hasn’t, and really what we’ve broken down is what we think the audience really wants, [what] the audience that loves Deus Ex is going to want to see out of a Deus Ex movie. And it’s not a rehashing of the game. What they want to see is, they want to see elements of the game that they love, but they want to see things that they hadn’t quite seen in the game, that the game didn’t allow them to see. So it’s really allowed us to expand upon the things that happened in the game, and the game has such a great cinematic story to begin with that those elements are very easy to extract. But really, at its core, we just keep telling each other, “We’re not making a video game movie, we’re making a cyberpunk movie.” And Scott and I are such big cyberpunk fans from way back in the day that that just really charges us up. Because that’s what’s so great about Deus Ex to begin with, is it really gets cyberpunk. I Eidos Montreal really understood the nature of cyberpunk and made “the” cyberpunk game, and it is just fantastic, and we’ve just had a great time adapting it.
