After her success in “Gravity,” Sandra Bullock is again orbiting a Warner Bros. project, Variety reveals.

Sources tell Variety that Warners has greenlit the political dramedy “Our Brand is Crisis,” which Bullock has committed to star in with David Gordon Green set to direct. The film is based on the 2005 documentary of the same name, which focuses on the use of American political campaign strategies in South America.

Bullock had been linked to the project as far back as awards season, but was still weighing her options. Insiders say that following a meeting with Green, who has been in the mix for the directing job for some time, the actress was convinced to join the project on the strength of his vision.

Bullock will also exec produce with George Clooney and Grant Heslov producing through their Smokehouse Pictures banner. Peter Straughan penned the script. Courtenay Valenti and Racheline Benveniste are overseeing the project for the studio.

Bullock is currently attached to the Sony pic “Tupperware Unsealed” which revolves around the inventor of Tupperware. Tate Taylor is on board to helm. Green’s most recent film “Manglehorn,” starring Al Pacino and Holly Hunter, will premiere at the Toronto Film Fest.
