Chris Pratt has always been one of the most lovable guys in show business. We first came to love him on Everwood, and in a key guest role on The O.C. But everyone properly fell in love with this comic genius when he starred as Andy Dwyer on Parks and Recreation. With a scruffy beard and a cuddly look, Andy worked his comically clueless way into the heart of April (Aubrey Plaza) and all of us at home.

Chris' movie career kicked into high gear with roles in Moneyball and Zero Dark Thirty, both requiring him to drop weight and bulk up to play a baseball star and a Navy SEAL, respectively. With a career on the rise Chris decided to go in the opposite direction, regaining his weight for a role in Delivery Man. But soon after Chris was once again swearing off beer and hitting the gym to get the incredible body he displayed in this years biggest box office hit, Guardians of the Galaxy. And the results were incredible. Check out his transformation over the years in the gallery above.

Watch Chris discuss what it was like stepping into the Marvel universe, below.
