Since J.J. Abrams is cruelly making us wait until next summer to see his top-secret, totally inscrutable Super 8, we guess we'll just have to make do with Christopher Nolan's semi-secret, increasingly scrutable Inception (due in July) to hold us over. Warner Bros. today released a third trailer for the movie, in which Leonardo DiCaprio plays a guy with the technology to enter people's dreams and steal their secrets (or something). This new teaser gives us a little more background and shows some Matrix-y in-dream sequences and shots of Joseph Gordon-Levitt flying that we've not yet seen before. But we're still in no real danger of understanding exactly what this thing is about. Looks good, though!
