The Cannes Film Festival, until 2003 called the International Film Festival, is the most prestigious film festival in the world.
Held in Cannes, France, it previews new films of all genres, including documentaries, from all around the world. Founded in 1946, the invitation-only festival is held annually at the Palais des Festivals et des Congrès. The festival was formally accredited by the FIAPF in 1951. From Wikipedia
