Who Are the Guardians of the Galaxy?

Chris Pratt trained extensively to play the part of Peter Quill, a human/alien hybrid and NASA astronaut who eventually takes on the identity of Star-Lord, policeman of the galaxy.

Of Peter, Chris said, "There's a petulance to him. He's not held accountable as an adult and free in space to do whatever he wants to do. He's definitely slept with some superweird aliens."

"My favorite moment was when I donned my first wardrobe. My walk changed, and I had a little extra bob in my step," Chris said.
