TRIVIA: Vin Diesel reprised his role providing the voice and motion of Groot, he agreed to have his body shrunk down to six inches during filming and be restored to normal size afterwards; reports are he spent most of his off-time on the set sleeping in a pet carrier.
I know they tend to release these trailers with unfinished CGI effects. I hope they fix Baby Groot's seeming indifference to gravity in the finished version. He's running like Sackboy.
Still, looks like a whole lot of big stupid fun, just like the first.
Guardians of the Galaxy, the movie that answers the question, "Can we make a movie with a soundtrack as obnoxious as Tarantino's, but without any taste?"
