"Actor Matt Damon is in talks to play Lance Armstrong in a biopic of the cycling legend.
The film, which has been in development for several years, 
will be based on Armstrong’s breathtaking 2000 auto- biography, It’s Not About the Bike, where the Texan discusses his childhood, battle with testicular cancer, recovery and his first Tour de France win in 1999. 
Actor Jake Gyllenhaal (of Brokeback Mountain fame) was initially linked to the project but is reportedly no longer under consideration". Source: www.theimproper.com
