Nick Saban the movie star

Alabama coach Nick Saban already had a cameo in the motion picture “The Blind Side.”

Now, he’s the star of his own documentary, “Nick Saban: Gamechanger,” which opens in theaters Friday. Here’s a video trailer for the documentary.

The premiere was Tuesday in Birmingham. The documentary was produced by Flashlight Media of Memphis, Tenn., and features footage from Alabama’s national championship run last season.
