Film brings Rock back to college days

Wrestler-turned-movie star Dwayne "The Rock" Johnson is set to return to the American football field to star in new film Gridiron Gang.

The hulking star, who was once a college American football star will get the chance to relive his youth in the film, which is about a counsellor at a juvenile detention centre who gains the respect of the teens when he puts them on a football team.

The film is based on a 1993 documentary about a real-life counsellor-turned-coach.
