Chris Pratt thinks 'Guardians of the Galaxy' will inspire the number one Halloween costume this year.

The 35-year-old actor - who plays Peter Quill in the new superhero blockbuster - is confident that younger viewers will love gun-wielding talking raccoon Rocket so much, they will all want to dress as him when the spooky holiday comes around on October 31.

He told MTV News: ''I think there are going to be a lot of people dressed up as Rocket this Halloween, a lot of kids.''

The 'Parks and Recreation' actor believes that, though Rocket is essentially there for comic relief, the creature's uniqueness also contributes to ''dramatic reality'' within the movie.

''This thing, as funny as it is to have a little talking raccoon with a machine gun running around being an a-hole, what really carries you through is the dramatic reality that there's nothing else in the universe like him.''

Chris is astonished by the quality of the computer-generated imagery (CGI) that has been used in the movie because it is so realistic.

He also said: ''This is CG unlike anything that I've ever seen before, it's so real.''
