Tim McGraw's new movie "The Blind Side" arrives in theaters today (showtimes). The film tells the story of Baltimore Ravens rookie Michael Oher, who seven years ago was a homeless teenager taken in by the Touhy family. With the support and stability the Touhys provided, Oher was able to get an education -- and excel on the football field. McGraw portrays Sean Touhy in the movie. The singer says that between the film's plot, crew, and cast, it was easy for him to sign on for the role.
