The newest trailer for Inception, currently running before Iron Man 2, is noticeably different from the bits Warner Bros. has previously released. Although it contains no earth-shattering spoilers, this trailer certainly attempts to draw out a clear narrative. Leonardo DiCaprio stars as a security agent who can enter people’s dreams and steal ideas. He enlists Ellen Page for help. Inception also co-stars Nolan favorites such as Ken Watanabe, Cillian Murphy, and Michael Caine.
