Fans eager to see what Marvel Studios has up their sleeve with Guardians of the Galaxy are in luck, because we now have word that the hotly anticipated first trailer for the film will debut next week, on February 18th. Guardians is Marvel's riskiest bet yet, since it's based on a comic few have ever heard of that features a ragtag group of cosmic ex-cons whose roster includes the green-skinned Gamora (Zoe Saldana), a talking raccoon named Rocket (Bradley Cooper), the dangerous Drax the Destroyer (Dave Bautista), a walking tree named Groot (Vin Diesel), and Parks and Recreation's Chris Pratt as the leader, Star-Lord.
