He is Groot!
Disney/Marvel just dropped an all-new trailer for Guardians of the Galaxy, and it's loaded with new goodies for fans of the utterly bananas comic book adaptation. But there's nothing they wanted more than to hear Vin Diesel say the giant tree-creature's signature line -- the only thing the the character ever says, actually -- and that is "I am Groot."
The new trailer debuted on the movie's Facebook page after a Q&A with cast members Chris Pratt, Dave Bautista, Karen Gillan and director James Gunn. The Marvel marketing team announced the trailer and hangout on Friday, the day they unveiled a stunning new poster for the film, which comes out August 1.
