Inception!

New Chris Nolan,

"Set within the architecture of the human mind."

Stars Leonardo Dicaprio, Joseph Gordon-Levitt, Ken Wantanabe, Marion Cotillard, Cillian Murphy,Ellen Page, Michael Cane and others. I must say I love this trailer, this looks like a very interesting piece of filmmaking.

Iron Man 2 trailer

Just saw this a few days ago, not sure when it officially dropped.
No shots of Rockwell as Hammer but damn Rourke looks like he is going to kill it as Vanko/ Whiplash.
Enjoy.
