Ken Watanabe, Tom Hardy Join Christopher Nolan's 'Inception'

Ken Watanabe in 'Batman Begins'Christopher Nolan has recruited another familiar face from Gotham City. According to The Hollywood Reporter, "Batman Begins" actor Ken Watanabe will reunite with Christopher Nolan (and fellow "Begins" actor Cillian Murphy) for "Inception," Nolan's mysterious follow-up to "The Dark Knight."

He's not the only new castmember. Tom Hardy ("RocknRolla") has also signed on, joining Leonardo DiCaprio, Joseph Gordon-Levitt, Cillian Murphy, Ellen Page and Marion Cotillard. Not surprisingly, the plot still remains under wraps, but THR reveals that Watanabe will be playing the film's villain, a man who is attempting to blackmail DiCaprio. Hardy will be playing a member of DiCaprio's "team," which should put him together with grad student Page and Gordon-Levitt. Murphy's role is still unspecified.

The cast continues Nolan's tradition of attracting and landing top-notch talent. He has clearly grown fond of reusing his actors, especially if they have been through the training ground of Gotham City. In addition to Watanabe and Murphy, it is rumored that Michael Caine might come aboard, which would make the fourth time the actor and director have worked together.

The film is expected to shoot this summer (which leaves a few more weeks to add more "Batman" cast members), and is aiming to hit theaters in 2010. Hopefully, we will get some real glimpses at the film so we really have something to talk about!
