The first trailer for the movie about Roy Keane's life has landed. 

The film will debut at the Galway Film Fleadh on July 12th, and tells the story of Roy's early days playing for his local club, Rockmount, in Cork, and aims to show the passion and drive that got Keane to the highest level in world football.

It's directed by Dave Tynan and stars Craig Keane Harrington as the young Roy, a boy possessed and obsessed with making the first XI of his team, and won't let anything stop him from achieving his goal.
