Ken Watanabe has joined the cast of "Inception," an upcoming film by Christopher Nolan that stars Leonardo DiCaprio. The movie is described as a "contemporary sci-fi actioner set within the architecture of the mind."

DiCaprio plays a CEO-like role, supported by a team that includes Ellen Page, Joseph Gordon-Levitt, Tom Hardy, and Marion Cotillard. Watanabe has been cast as the villain, a man blackmailing DiCaprio.

This is Watanabe's second time in a film by Nolan, as he previously appeared in "Batman Begins" in 2005. "Inception" is dated for 2010.
