"Guardians of the Galaxy" (2014)
When Marvel decided to stop selling it's characters to outside movie studios and begin making their own movies, starting with Iron Man seemed like a bold choice at the time. Outside of comic fans he wasn't as well known as say Spider-Man or the X-Men. That choice paid off and audiences responded to their other films and soon the Avengers were household names. With all this goodwill they had banked, Marvel decided to see how far that really went by making a movie about the Guardians of the Galaxy.
Despite what a lot of people may think, the Guardians aren't new exactly. The first team was from an alternate future in the 31st century. The modern incarnation of the team (Star-Lord, Gamora, Rocket Raccoon, Drax the Destroyer and Groot) in 2008. The team came together following Marvel's first "Annihilation" cosmic event.
"Guardians of the Galaxy" stars Chris Pratt, Zoe Saldana, Dave Bautista, Karen Gillan, Lee Pace, Benicio del Toro, John C. Reilly, Glenn Close and the voices of Bradley Cooper and Vin Diesel. The screenplay was written by James Gunn and Nicole Perlman and directed by James Gunn. The film was released in theaters on August 1, 2014.
