Chris Pratt has revealed how he got in shape for his role in Guardians of the Galaxy.
The actor, who stars as Peter Quilaka Star Lord in the Marvel sci-fi movie, confessed that he had to put in a lot of hard work into whipping his body into shape for the part.
Asked by David Letterman on The Late Show if he was taking good care, Pratt said: "No, I am not. For almost my entire life that has not been the case but for this movie I did have to take care of myself for a while but that's quickly going to go away."
Looking good on-screen didn't come easy, the actor revealed. "There's some airbrushing and a lot of sit-ups and sort of starving yourself knowing that you had a shirtless scene coming up."
The 35-year-old actor also said that he was worried about whether the film would be good once all the different elements were put together.
He said: "I saw it for the first time about two weeks ago and with a movie like this where two of the characters are animated and every world has at least some element of CGI, I kind of didn't know whether it was going to be good or not.
"I remember having a hunch we were doing something special when we shot it a year ago but I walked into the theatre pretty nervous and I'd been having all these nightmares that I was going to hate the movie but I saw it for the first time two weeks ago and really, really loved it."
