Director James Mangold talks to RTÉ Entertainment's John Byrne about his new film Le Mans '66, which stars Matt Damon and Christian Bale.

The movie's based on real-life events, as automotive designer Carroll Shelby (Damon) and race car driver Ken Miles (Bale) lead a Ford team who set about building a race car that can beat legendary Ferrari.

Ultimately, they produce the Ford GT40 for a showdown at the 1966 24 Hours of Le Mans.
