Sandra Bullock, Bradley Cooper vie for top box-office spotLos Angeles, Oct 30 (AZINS) "Our Brand is Crisis" and "Burnt", two new movies with Sandra Bullock starring in one and Bradley Cooper in the other, premiere in the US this weekend, though showbiz pundits predict that "The Martian" and "Goosebumps" will be the big box-office draws for another week.

"Our Brand is Crisis", directed by David Gordon Green, is a political satire in which Bullock plays a consultant charged with rolling out a media campaign for a presidential candidate in Bolivia.

The film is based on the like-named documentary about the application of American political campaign strategies in the Bolivia of 2002, when Gonzalo Sanchez de Lozada beat Evo Morales and was re-elected president.

"Burnt", by John Wells, tells how a chef (Cooper) whose career was wrecked by drug addiction and his in-your-face attitude, decides to turn his life around and completely redeem himself as head chef of one of London's finest restaurants.

The film brings Bradley Cooper and Sienna Miller back together on the big screen a year after their big hit "American Sniper".

Also making their debut are the terror comedies "Scouts Guide to the Zombie Apocalypse" and "Freaks of Nature".

In "Scouts Guide to the Zombie Apocalypse" by Christopher Landon, three young explorers discover the true meaning of friendship when they try to save their own town from a zombie menace.

In the cast are Tye Sheridan, Logan Miller and Joey Morgan.

"Freaks of Nature" by Robbie Pickering shows humans, vampires and zombies living together peacefully in a town called Dillford, until some extraterrestrials arrive and plan to exterminate every last one of them.

Nicholas Braun, Mackenzie Davis, Josh Fadem and Denis Leary star.
