Animal Magnetism: Seth Rogen's had to make some mainstream concessions to get in fighting shape for The Green Hornet, but they're nothing compared to how he responded to the threat of a Zack and Miri sex scene. "I shaved my back just in case," he told WENN. "I went fully bare, like a two year old. I was ready. I didn't want to be too real for the world. I don't think the world is too ready for a hairy back in a love scene." We'd make an easy Robin Williams joke here, but Rogen beat us to the punch: "Has there ever been a sex scene with Robin Williams? People don't want to see that. That would border on bestiality." [OK!]
