The movie, about Tamil refugees trying to find a better life in France, picked up the festival's top honour on Sunday (24May15) as this year's celebration came to a close.

Accepting his award from jury presidents Ethan and Joel Coen, Audiard dedicated the Palme d'Or to his father, stating, "I'm very moved. Winning a prize from the Coen brothers is something that is exceptional."

It was a good night for French film and French talent - Vincent Lindon was named Best Actor for his role in director Stephane Brize's film La Loi du Marché (The Measure of a Man), while French actress Emmanuelle Bercot shared the Best Actress prize with American Rooney Mara.

Bercot was honoured for her role in Mon Roi (My King), while Mara picked up her half of the prize for her part in Todd Haynes' acclaimed Carol.

Hungarian director Laszlo Nemes' Palme d'Or favourite Saul Fia (Son of Saul) was the jury's runner-up film of the festival.
