It's final - Sandra Bullock will star in "Our Brand is Crisis".

After she has weighed all her options and met with its director, David Gordon Green, she has agreed to do the political dramedy movie. According to Variety, the Oscar winner has finally decided to work on the project "on the strength of his vision".

Bullock has been linked to the project since last year. The Wrap reported that she and Clooney have made discussions about the movie while they were doing promotional rounds for "Gravity". But at that time, the actress is said to be thinking about two projects. "The Perfect Heist" is one of them.

The Sandra Bullock starrer "Our Brand is Crisis" is based on the 2005 documentary of Rachel Boynton. It revolves around the usage of American political campaign tactics in Bolivia by James Carville and Stan Greenberg, former consultants of then US President George Clinton, to help Gonzalo Sanchez de Lozada win in the election as president.

Checkout the trailer of the documentary below:

Sandra Bullock will play the role of "Calamity" Jane Bodine in "Our Brand is Crisis". She is a retired American political consultant who every so often quotes prominent personalities to prove her point. She will also function as the executive producer of the film, along with George Clooney. Grant Heslov will serve as producer. What is unknown at this time is whether Clooney, her co-actor in the hit project "Gravity", will also play a role in this new Warner Bros. Pictures film.

Central Casting Call Louisiana has announced the open casting call on Sept. 3 for background actors who will portray the role of Bolivian men and women of all ages. Aside from this, the movie producers are also looking for crew members. Filming is said to begin on Sept. 29.

"Our Brand is Crisis" is written by Peter Straughan from "The Men Who Stares at Goats".
