An update on the casting of Christopher Nolan's Inception:
Ken Watanabe has been cast as the villain of the movie, which Nolan vaguely and teasingly described as a psychological thriller about "the architecture of the mind." You might remember Watanabe as the Japanese general in Clint Eastwood's Letters From Iwo Jima, or as Tom Cruise's Samurai-sword-wielding better half in The Last Samurai.
Tom Hardy, who portrayed the villain in Star Trek: Nemesis, has also been signed. He'll play an associate of Leonardo DiCaprio's successful businessman, who will most likely be the protagonist.
Hardy and Watanabe join a cast that also includes Marion Cotillard, Ellen Page, Cillian Murphy, Joseph Gordon-Levitt, and Michael Caine.
