Dave Franco, "Neighbors"
Dave Franco's first onscreen sex scene started and ended in embarrassment. He had a huge pimple right on his butt during the day of filming. He barely knew his co-star, Halson Sage, and "of course, I woke up that morning and I had a giant pimple on my ass," he said. "I had to go to the makeup artist who I had also just met that week and be like, 'Can I go in the other room and have you put makeup [on it]?'"
