Box office ticket sales for summer 2014 movies went from a June swoon to an even worse July, with the July 4th weekend box office falling a staggering 44% compared to 2013. If there's hero to save the day, it just may be a Marvel Comics adaptation featuring a title most people had never heard of. We're speaking, of course, about the Guardians of the Galaxy, who have become a little less obscure thanks to online buzz and the release of various trailers. The newest extended trailer -- released this week from Marvel Entertainment -- is set to the Runaways' "Cherry Bomb" and features plenty of action, one-liners, and an entertaining exchange between Star-Lord (Chris Pratt) and Rocket Raccoon (voiced by Bradley Cooper). Also starring Zoe Saldana, Dave Bautista and the voice of Vin Diesel, Guardians of the Galaxy hits theaters August 1st.
