Actor Chris Pratt plans to visit sick children while dressed as his superhero character from new movie Guardians Of The Galaxy after taking his costume home when the cameras stopped rolling.

The actor plays the space superhero group's leader Peter Quill/Star-Lord, and dons an iconic red jacket as he attempts to save the world.

In an interview with Panzer Tv promoting the film, Pratt reveals he secretly took his costume from the set in order to do good following the movie's release.

He admits, "I stole the jacket and some of the wardrobe so that, if this movie comes out and does what everyone hopes it can, I can follow the example of someone and go visit kids.

"If it was a big enough movie, to where it would mean something to a kid who's sick in the hospital - for Peter Quill or Star-Lord to come visit them - I'll do that. I think that's awesome, man. That would give me real meaning for this movie, you know?...

"Right now, it means high profile, cool jobs coming up, big press tour, and all the excitement of it all. But none of that really means anything. The coolest things would be that my son can one day see this, and that maybe I can go affect some kids in a positive way; be a good role model for them."

Guardians of the Galaxy, which also stars Zoe Saldana, Bradley Cooper, Dave Bautista and Vin Diesel, opens on both sides of the Atlantic on Friday (01Aug14), and studio bosses have already announced a sequel, which is expected to hit cinemas in 2017.
