A documentary about the world's waste and a musical about an Australian aboriginal singing group are among seven films added to the lineup of the Cannes Film Festival.

"Trashed," by British director Candida Brady, will have a special screening at the May 16-27 festival, while Australian director Wayne Blair's "The Sapphires" joins the midnight movies roster along with Franck Khalfoun's Franco-American horror remake "Maniac."

Organizers added three films Monday to the festival's Un Certain Regard sidebar — "Djeca," by Aida Begic from Bosnia-Herzegovina; "Renoir," by France's Gilles Bourdos; and "Gimme the Loot," Adam Leon's film about Bronx graffiti artists.

The Cannes lineup also includes "Final Cut," a montage film produced by Hungarian auteur Bela Tarr.
