Who or what will they be playing is not known. Jim Carrey will soon have some superhero credibility when stars in Kick Ass 2 as Colonel Stars and Stripes. Adam Sandler, on the other hand? Let's not go there. I'm not a fan, so let's leave it at that.
I'm not too familiar with the Guardians of the Galaxy comic book but am digging the fact that James Gunn (Super, Slither) is directing. That's actually what I'm most excited about, because in my eyes he can do no wrong. *swoons*
Guardians of the Galaxy is set to be released August 1, 2014.
