Any good actor knows the importance of researching a role.
For Magic Mike costars Matthew McConaughey and Channing Tatum, that meant delving into male strip clubs – for business, not pleasure, McConaughey, told reporters at the premiere of his latest movie, Bernie, in which he costars with Jack Black and Shirley MacLaine.
Speaking of Magic Mike, McConaughey, 42, said, “[We] met early on and went by one male review strip club in New Orleans, I was there for about an hour. That was enough.”
Tatum, 31, actually was a male dancer before he acted. In Magic Mike, which opens June 29, McConaughey plays Dallas, the enterprising strip club owner. “Dallas wants to take over, world domination with his male revue,” said the actor. “It was fun and very, very corny.”
