Chris Pratt Talks Hilarious 'Guardians of the Galaxy' Workout Routine

Writer and director James Gunn repeatedly points out that Marvel Studios is finding success in adapting obscure characters to the big screen by selecting actors who are right for the roles as opposed to actors who from a business perspective may be more marketable. It's that thought process that let Gunn make the unusual, yet inspired casting choice of Chris Pratt as the lead in Guardians of the Galaxy over dozens of others who auditioned.

When first cast, some fans of NBC's Parks and Recreation didn't find Pratt to be in "superhero shape" for such a role, but the actor's workout regiment for his supporting role in Zero Dark Thirty helped prove otherwise. Then came the photo...

Two weeks ago, before stepping into the spotlight with castmates at Comic-Con this weekend, Pratt tweeted an image of him topless. He admitted doing so was "douchey" and that his brother convinced him to do it to show fans that he's taking the physical aspect of the Guardians of the Galaxy job seriously, so while at Comic-Con he was asked about it.
