Hugh Jackman went on the BBC's Graham Norton Show recently and told the out chat-show host about having to be naked for a pivotal scene in one of the first X-Men movies. "I jokingly asked for a closed set," Jackman recalls. "As a I turned the corner, the first assistant director had all the female crew members assembled waving five-dollar notes."

His Days of Future Past costars Michael Fassbender and James McAvoy, meanwhile, got off easy—they only had to talk about their characters signature poses. We're still waiting for the scene where Professor X, Magneto and Wolverine meet up in a Russian bathhouse.
