Zoey Saldana doesn't mind changing her body for better work. The 35-year-old actress said in an interview at Comic-Con that she's finding more "meaty" female roles in science-fiction than in earthbound movies. The actress portrays green-skinned alien Gamora in Marvel's "Guardians of the Galaxy" after going blue in James Cameron's "Avatar." Big Bang Theory star Johnny Galecki gave the room a jolt when he revealed himself to a Comic-Con crowd that thought they were just going to listen to the writers talk about the hit show, not have one show up disguised as a Star Wars character. Who said that three's a crowd? Kate Upton, Cameron Diaz and Leslie Mann showed off their amazing bikini bodies while shooting for their upcoming flick The Other Woman.
