As Usain Bolt celebrates winning the gold in the men's 100m final, a new documentary celebrating the sprinter's life has been released.

Usain Bolt - The Movie is a behind the scenes look at the life of the fastest man on earth and what makes him strive for excellence.

French director Gael Leiblang spent a year with the Jamaican runner talking to him as he prepared for the London 2012 Olympics.

The film also speaks to the athlete's close friends and family who have supported him on his quest to remain an Olympic record holder.
