'The Program': Chris O'Dowd Backs Ben Foster's Decision To Take Performance-Enhancing Drugs To Play Lance Armstrong

Chris O'Dowd has backed his ‘The Program’ co-star Ben Foster’s decision to take performance-enhancing drugs to help him play shamed cyclist Lance Armstrong.

Ben’s method acting has seen him following Armstrong’s doping programme in order to better understand the role - something that Chris has hailed as “a really smart thing”.

Ben revealed he’d been taking the drugs - which are not illegal, only banned in sport - last week, under the close supervision of a doctor.

However, he claimed he’d “nearly lost his f***ing marbles” taking them.
