Olivia Munn
Olivia Munn appeared topless in Magic Mike, but she said that she wouldn't do it for just anyone. “There are very few directors I would ever do it for,” she explained to Vulture. For her, it made sense for the character to be topless at that moment. As long as it's tasteful!
Mark Wahlberg
Fun fact: Mark Wahlberg actually wore a prosthetic penis in the movie Boogie Nights. The only time he truly bared it all was in Broken City. He told the director that if the sex scene was cut, he would strip down nude. He'd rather get naked for the world to see than to have to kiss someone other than his wife!
