Yahoo! Movies has the first official teaser trailer for Christopher Nolan‘s new movie, Inception. No one really knows exactly what the movie is about except that it deals with a CEO (Leonardo DiCaprio) being blackmailed, and, as you will see, that it’s a type of science fiction movie that deals mainly (and possibly inside) the human mind. It has a huge supporting cast, including Michael Caine, Marion Cotillard, Cillian Murphy, Ellen Page, Joseph Gordon-Levitt, Ken Wantabe, and Tom Berenger.

It has become something of a tradition for Nolan to do a smaller movie in between the juggernaut that is the current Batman franchise. After Batman Begins, he did The Prestige; after The Dark Knight, he’s doing Inception. It’s still unclear what the future holds for a Batman 3, and if Nolan will even be involved, but it is expected after the dust settles from this project. The director first made a name for himself with the 2000 film Memento, and followed that up with 2002’s Insomnia.
