Sean Penn used his clout as head of the Cannes Film Festival jury to issue a presidential proclamation: See this documentary.

Penn's pick, added to the festival roster at his special request, is a low-budget documentary filmed by volunteers who went to Sri Lanka to help victims of the 2004 tsunami. Rocker Bono, filmmaker Michael Moore and actresses Natalie Portman and Faye Dunaway showed up at the movie's premiere Friday in Cannes, France.

"The Third Wave" was directed by Alison Thompson, who chronicled her journey to Sri Lanka just days after the tsunami hit.
