If all you know about “Magic Mike” is that it’s a movie about male strippers, you are in for a surprise. Firstly, the film is loosely based on star Channing Tatum’s life as an exotic dancer before he became a model and then an actor. Secondly, at heart it’s a story about a man who has to choose between living an easy life following the path his mentor has laid out for him, or growing up and striking out on his own.
