The Cannes Film Festival says brothers Joel and Ethan Coen will be the festival jury's first joint chairmen.
In a statement, the festival said the nomination of the men who made Raising Arizona, Fargo and Barton Fink - which won the prestigious Palme d'Or - is part of its celebration of all "cinema brothers."
The Coen Brothers said: "We look forward to returning to Cannes this year. We welcome as always the opportunity to watch movies there from all over the world. Cannes is a festival that has been important to us since the very beginning of our career. Presiding over the Jury is a special honor, since we have never heretofore been president of anything. We will issue further proclamations at the appropriate time."
As well as winning the Palme d' Or in 1991 for Barton Fink, the Coen brothers scooped the festival's Grand Prix in 2013 for Inside Llewyn Davis. They've also won Best Director twice - in 1996 for Fargo and in 2001 for The Man Who Wasn't There.
The Coens are currently working on their new film Hail Caesar!, starring George Clooney, Christophe Lambert, Scarlett Johansson, Tilda Swinton, Josh Brolin and Channing Tatum.
The 2015 Cannes Film Festival takes place May 13-24. The official lineup and jury of the 2015 festival will be announced in April.
