Leonardo DiCaprio, not Christian Bale, will topline Christopher Nolan’s next project. Don’t worry, it’s not a Batman movie.

The film is his previously announced sci-fi flick Inception. HR reports that DiCaprio has been hired as Nolan’s lead. No we still don’t know what it’s about, and so we have no idea what kind of character DiCaprio will be playing. The closest anyone has come to a plot description is offered up in a press release hinting that the movie takes place within “the architecture of the mind.” Maybe he’s remaking The Cell.
