A formal announcement hasn’t been made, but we’ve just learned that Warner Bros’ Green Lantern and Sucker Punch are set to be released in 3D. Over at Box Office Mojo, they’ve updated the slate for several of the studio’s films, and they’ve listed those two as 3D releases alongside Harry Potter and The Deathly Hallows (Part 1 & 2) and Legend of the Guardians.

Both films are listed as Green Lantern (3D) and Sucker Punch (3D), with release dates scheduled for June 17, 2011 and March 25, 2011 respectively. We’re not clear on whether or not the films will be shot in 3D or converted later, but we do know that Martin Campbell is set to start production on Lantern fairly soon.

As for Sucker Punch, it’s a Zack Snyder directed female ensemble about a young girl committed to an insane asylum, who dreams of escaping with the help of her fellow inmates. The leader of the pack is Baby Doll, a girl who’s step-father plans on having her lobotomized in five days. Does that premise warrant 3D?

None of the major superhero movies have really taken advantage of 3D (are we counting Superman Returns?), so Green Lantern might be one of the first to venture into that world. Iron Man and The Incredible Hulk did well without it, so I wonder if it will come off as a bit gimmicky?

Are you interested in seeing either of these films in 3D? Do you think they should be left in the traditional format?
