(R) Supposedly inspired by Channing Tatum's early experience as a male stripper, the movie exposes a seamy back story of the industry as Mike (Tatum) passes his strip-knowledge on to a young protegee (Alex Pettyfer), while trying to maintain a normal relationship with his family, friends and girlfriend. Also naked: Matthew McConaughey. (Mostly because he's contractually obligated to be naked or half-naked in every movie he does.)
