Oh brother! The sibling duos who dominate film

Cannes : From the Warner and Lumiere brothers to the Boultings, cinema has been marked from its earliest days by remarkable sibling double acts.

The Safdie brothers -- Ben and Josh -- are the latest directing duo to hit the headlines, the big surprise of this year's Cannes film festival, which opens on Wednesday.

The New Yorkers, whose new grindhouse movie "Good Time" was described by its star Robert Pattinson as a "mentally damaged psychopath bank robbery movie", are the most eye-catching newcomers in the running for the festival's top prize, the Palme d'Or.

They join a long list of brothers from the kings of low-brow comedy, the Farrellys, to the Coens who have worked together behind the camera.
