Save the llama! Sandra Bullock and Billy Bob Thornton go to any length to control a Bolivian election in Our Brand Is Crisis trailer

By design, no one ever sees the people who engineer the publicity that can determine elections.

The trailer for a new movie, Our Brand Is Crisis, however, focuses on the machinations of two political operators - played by Sandra Bullock and Billy Bob Thornton - as they attempt to determine the outcome of the 2002 Bolivian presidential election.

For the 51-year-old actress' character, that outcome seems to hinge on publicity, the tears of a politician, and a llama with stage fright.

Sandra plays 'Calamity' Jane Bodine, a political and advertising consultant hired to run the campaign of Pedro Gallo, one of the two main candidates for the Bolivian presidency.

Comedy and drama both follow in a campaign that almost immediately becomes cutthroat and could eventually turn deadly.

'There's only one wrong in this! Only one wrong! And that is losing!' Jane screams at her Bolivian team before realizing that none of them speak English.

Jane does have some success though, after she convinces Gallo (Joaquim de Almeida) to shed a tear during a televised interview.

Success is harder to find when Jane tries to film a television ad for Gallo and has to watch helplessly when the llama star of the commercial breaks free and runs into the street.

'It's like he killed himself rather than be in one of our commercials,' Jane tells a colleague in despair.

Challenge: Seen as being out of touch with the common people, Jane has to market Gallo to make him more appealing

Since she is opposed at every step by her opposition counterpart, Pat Candy (played by Billy Bob), those victories involve constant fighting.

There could be negative consequences to this: 'If you fight with monsters for too long, you become a monster,' Candy informs Jane at one point.

Protests and controversy seem to escalate later in the trailer, indicating that Jane's actions might indeed have monstrous consequences.

The darker themes hinted in this part of the trailer may tease at the real-world situation that inspired Our Brand Is Crisis.

In 2005, Rachel Boynton's documentary of the same name revealed the marketing strategies employed by the firm of Greenberg Carville Shrum in the Bolivian election.

Thanks to winning candidate Gonzalo Sanchez de Lozada's later deadly response to protests among the Bolivian population, the campaign itself had human-rights implications.

Directed by David Gordon Green and produced by George Clooney and Grant Heslov, Our Brand Is Crisis will be released on October 30.
