If you thought the Mission: Impossible — Ghost Protocol teaser was exciting, wait until you get a peek at the full-length trailer. The plot of the film is a bit clearer this time around (we even learn what "ghost protocol" is!), and there's a closer look at the rivalry between Ethan (Cruise) and Brandt (Jeremy Renner).
What I love most about this preview is that it's actually funny, thanks to Simon Pegg, but the real kicker is watching Cruise run down the side of a building like it's no big deal. The film hits theaters Dec. 21, but watch the new trailer when you read more.
