Collider has an extensive interview with G.I. Joe producer Lorenzo di Bonaventura. I've included a few of the newsworthy tidbits below:
The film will be rated PG-13 and will feature bloodless violence.
Defending the choice of director Stephen Sommers: "He's just... his enthusiasm, his excitement, his sense of adventure, his embracing of the mythology, his understanding of the characters."
The movie will feature "2 or 3 really big" set pieces :and a couple of sort of medium/small ones."
Each character has more than one outfit, aside from Snake Eyes.
On the tone of the film: "I guess it's definitely a comic book movie and it's definitely has a great sense of humor, so there's a lot of humor and a lot of drama and a lot of action. "
Production moves to Prague on May 8th. Prague will serve as 2 or 3 locations from around the world.
On The Pit: "I think everybody's going to be really happy that we took The Pit very seriously and built it to fulfill anybody's sense of fantasy of what it could be."
