Behind the Scenes of 'the Greatest Fraud' in Sports

Alex Gibney is an Academy-Award winning director who was given unparalleled access to Lance Armstrong. His original project was a documentary film about the world-champion cyclist's training for an eighth Tour de France title after a four-year hiatus. Now a very different film is being released. As Gibney was preparing The Road Back, Armstrong's fellow cyclist, Floyd Landis, told ABC that Armstrong's career was based on illegal doping. After denying it for years, Armstrong finally confessed it all to Oprah Winfrey. The film now being released is The Armstrong Lie.
