Lance Armstrong Film 'Is Anatomy Of A Lie'
A documentary which claims to show the extent to which disgraced cyclist Lance Armstrong hid his use of performance enhancing drugs is to premiere at the London Film Festival.
The Armstrong Lie, directed by Alex Gibney, followed the 42-year-old as he attempted to make his comeback into cycling in 2009.
Initially, the documentary was meant to be an inspirational film about the former Tour de France champion.
But shortly before it was due for release, Armstrong was the subject of a federal investigation and eventually admitted doping during a prime-time interview with chat show host Oprah Winfrey.
Mr Gibney told Sky News: "We went back into the footage that we had shot and realised we had seen some extraordinary things.
"What we had was this footage of the anatomy of a lie. How he hid in plain sight (and) this spectacular myth that he was clean.
"I think that what made people angry in a way was not that he said, 'Look, I never tested positive', but that he said, 'How dare you say that I, as a cancer survivor, would ever use performance enhancing drugs?'"
Mr Gibney, 59, won an Academy Award in 2007 for best documentary feature with his film Taxi To The Dark Side, which focused on a taxi driver in Afghanistan who was killed in 2002.
Armstrong was stripped of the seven Tour de France titles he won between 1999 and 2005.
