A new behind the scenes look at Guardians of the Galaxy has arrived. Clocking in at a minute long, the video features the main cast of Chris Pratt (Star-Lord), Zoe Saldana (Gamora), Dave Bautista (Drax the Destroyer), Vin Diesel (Groot) and Bradley Cooper (Rocket Racoon), along with producer Kevin Feige, briefly discussing the Guardians as a gang of antihero outcasts and how the film will expand the Marvel Cinematic Universe. Unfortunately, though there's footage of the Groot and Rocket CG models synced to Diesel and Cooper's studio performances, we still don't get to hear their voices in action. Guardians of the Galaxy arrives in theaters August 1. Via Yahoo!
