"[What] we are looking at doing is developing a videogame based on the world of the film, which has all kinds of ideas that you can't fit into a feature film," Nolan explained. "That's something we've been talking about and are looking at doing long term, in a couple of years." That sounds promising, but we feel compelled to inform Mr. Nolan that Tim Schafer and Double Fine beat him to the punch, like, five years ago.
Still, the film's impressive take at the box office ($753 million so far) might give an interactive follow-up a large, interested audience. Oh, and the fact that a game wouldn't be pressured into launching alongside a movie (this one would be years late!) would be the source of more ... optimism than usual.
