When producers of “The Full Monty” went out looking for a cast, they purposely went looking for actors who couldn’t dance. But wouldn’t it have been easier to teach real dancers to fake like they couldn’t really dance? No. “You have to go back to a time when you couldn’t dance, when your leg wasn’t straight, your arms were not always in the right position. Some dancers can’t do that. It’s like asking somebody who’s learned how to walk, ‘Don’t walk.’ It’s difficult.”
