Unsurprisingly, they're focused on the man himself, with Ben Foster (3:10 To Yuma) in the iconic yellow Tour leader jersey and custom Trek as Armstrong, the man who came back from cancer to win the Tour de France seven consecutive times, only to be stripped of those titles for his doping offences.
Chris O'Dowd (Bridesmaids) plays the Irish sports journalist David Walsh, who was raising questions about Armstrong's performance long before the rest of the world began to follow suit. Jesse Plemons, of Friday Night Lights and Breaking Bad fame, and Guillaume Canet (Tell No One) will also appear. Our guess is that Plemons will play one of Armstrong's US Postal Service teammates and Canet a French rival. Admittedly blatant national stereotyping as their roles remain to be confirmed.
John Hodge, best known for his work with Danny Boyle, wrote the screenplay, and shooting should continue for the next few months well into the early spring.
In the meantime, if you need a fix of cycling scandal, keep your eyes peeled for a documentary into the affair with Alex Gibney's The Armstrong Lie, recently screened at the London Film Festival and due out here on 31 January.
