It has been a marketing blitz for the upcoming Marvel feature Guardians of the Galaxy. The full length trailer has hit the Internet and fans are wanting more from the upcoming film.

One the things that fans were upset about was that in the trailer Rocket Raccoon and Groot, who will be voiced by Vin Diesel could not be heard speaking. 24 hours later Marvel answers fans demands and posted some behind the scenes work of Bradley Cooper voicing, Rocket Raccoon, Variety reported.

It has now been reviled what the voice of Rocket Raccoon will sound like.

“Rocket has some real anger issues. This is the kind of movie I like to see. There’s nothing like it, that’s for sure,” said Cooper in regards to working on the film and his character, MTV reported.

Guardians stars Chris Pratt, Bradley Cooper, Vin Diesel, Zoe Saldana and is being directed by James Gunn.
