Alex Gibney and Frank Marshall Talk Making 'The Armstrong Lie'

Oscar-winning documentarian Alex Gibney and uber-producer Frank Marshall talk about how they were seduced by "the beautiful life" of Lance Armstrong while making an uplifting movie about his 2009 come back. The filmmakers go into detail about how they shelved that film then remade it -- adding new material -- to make their new movie, The Armstrong Lie.
