He added: "I am humbled and delighted to return to Cannes as President of the Un Certain Regard Jury. Even more than making films myself, discovering the work of talented filmmakers has always been at the very heart of both my personal and professional journeys.
"I see, in this responsibility I'm assigned, the opportunity to focus with the members of the Un Certain Regard Jury on an essential aspect of the art of film: stories told truthfully."
