“What is incredible about what they did is, they talked to David Fincher, they talked to Jim Cameron, I connected Jim and Alfonso for that. And what Alfonso is trying, is so insane. And Jim said, well, look, you’re about five years into the future…it’s too early to try anything that crazy. And they did it! I think he would kill me if I reveal [what is so crazy about it], and in time it will be publicized, but I think that in the same way that he pushed the narrative in Children of Men…[they] are absolutely pushing a new boundary in filmmaking, completely mind-blowing. And they way they’re making [Gravity] will I think foverever change certain types of productions. The engineering and the ingenuity of the machines they’ve created to film that way is fantastic. I’m amazed at Alfonso in the last few movies, because he has completely transformed himself.” — Guillermo del Toro on Cuaron’s upcoming sci-fi flick Gravity.
The speculation is that Cuaron is making a one-shot movie featuring Sandra Bullock in space. That would be kind of mind blowing.
