Director James Gunn was recently interviewed and discussed Marvel Studios' upcoming sci-fi project Guardians of the Galaxy.

The helmer revealed the filming location and schedule.

"Shepperton we're filming at. We're not filming right now, we start filming at the end of June."

He went on to talk about the comparison to Star Wars and some of the concept art released with the Marvel Cinematic Universe: Phase One - Avengers Assembled (10-Disc Limited Edition Six-Movie Collector's Set).

"I do think we're very, very different from Star Wars. Some of the concept art that came out is under my tutelage, and some of it is before my tutelage. The concept art that came out is only stuff that was on the big Marvel collected disc set, talking about phase two and it had some stuff from Guardians. Some of the art by Charlie Wen and the guys. The Rocket Racoon that was by itself was an early version of my Rocket that I dealt with Charlie when developing. He doesn't look so much like that anymore, but there's a lot of similarities in that he's more of a grounded, real little creature as opposed to a cartoonish thing."

Here is what he said when asked about the firearm-wielding alien raccoon in the film.

" I've done a lot of studying with real racoons, and we had real racoons come in. We've done photography with them, I've played with racoons, and fed racoons, and dealt a lot with real racoons to get some of the behaviour down, because it's really, really important to me that Rocket Racoon, who is the heart of the movie, is not a cartoon character, it's not Bugs Bunny in the middle of The Avengers, it's a real, little, somewhat mangled beast that's alone. There's no one else in the universe quite like him, he's been created by these guys to be a mean-ass fighting machine."

He also addressed the similarities to Marvel's The Avengers.

"In terms of a lot of stuff we're very much like The Avengers, where it's a very big, huge movie. It's different because it's cosmic, it's in outer space, it's very colourful. We have a whole history of science fiction behind us that we're dealing with, and borrowing from, and also fighting with to create something unique. But at the same time there's a lot of stuff it has in common with The Avengers."

He wrapped up the interview by talking about the addition of Chris Pratt and how he came to fill the role.

"Everybody knows Chris Pratt is in the movie, and I saw maybe 80 to 100 guys read for Peter Quill. I was very specific that I wanted it to be somebody really extraordinary. I really had Robert Downey Jr in mind a lot. You had this guy who came in and he inhabited Tony Stark, when you first saw Tony Stark he blew your mind, you couldn't believe what you were seeing. I knew that I needed somebody to blow my mind like that. We saw a lot of very famous guys for the role, a lot of very well-known people, and very, very good actors. We saw a lot of good performances, but it wasn't until Chris came in and he read and I was like, 'oh my God', this guy has his own, very particular, amazing take on the character that blew my mind, blew me away. Then I thought, this is the first guy I could see sharing the screen with Robert Downey Jr and giving him a run for his money."
