Hear Bradley Cooper As GUARDIANS OF THE GALAXY’s Rocket Raccoon

Marvel begins trotting out the briefest of behind-the-scenes featurettes.

One thing missing from yesterday's great Guardians of the Galaxy trailer: any dialogue from non-Star Lord and non-Nova Corps people. We especially wanted to hear more from Rocket Raccoon and Groot, who are being voiced by Bradley Cooper and Vin Diesel. Well, we get some of that now - Marvel has released a slight Rocket-focused clip that has Cooper's voice coming out of Rocket's mouth and includes some more VFX test footage of the character.

Remember, the nature of CGI means that they will be working on Rocket until the minute this movie is first screened, so that's why they're including test footage here. What you saw in the trailer was probably a big chunk of what they have completely finished (and that's stuff they had in process in July, as they showed it to us at Comic Con). By the way, in the quick clip - is Rocket talking to a prison crowd and claiming someone as his booty?
