Marvel has released three new character posters for James Gunn's Guardians of the Galaxy. We've got Rocket Raccoon, Groot and Gamora looking all kinds of badass. The director released the posters on Twitter today. The rodent is voiced by Bradley Cooper in the epic looking sci-fi space adventure, and I'm looking forward to seeing audiences react to him. I seriously doubt that Marvel has even shown the best parts of this character in any of the trailers or videos that have been released. I can't wait to see Rocket completely unleash the fury! Groot is voice by Vin Diesel and Gamora is played by Zoe Saldana. Guardians of the Galaxy will be released on August 1st.
