Just a few weeks after Sandra Bullock was cast as the lead in Our Brand Is Crisis, Scoot McNairy has joined the cast. No details have been released for the characters Sandra Bullock and Scoot McNairy are playing.

The project is based on the 2006 documentary of the same name, which explores how American political campaign techniques are being used in South America. The documentary, directed by Rachel Boynton, centered on U.S. campaign strategists who helped elect the president of Bolivia, and the aftermath that followed.

David Gordon Green (Joe) is directing from a screenplay by Peter Straughan (Tinker, Tailor, Soldier, Spy, Frank). George Clooney and Grant Heslov are producing through their Smokehouse Pictures company, with Sandra Bullock serving as an executive producer. Shooting is slated to begin sometime this fall.

Scoot McNairy can currently be seen in the indie comedy Frank, and he reunites with Argo star/director Ben Affleck in next month's Gone Girl. He is currently shooting Batman v Superman: Dawn of Justice in Detroit. The actor also starred on the recent AMC series Halt & Catch Fire.
