Quebec filmmaker Xavier Dolan has swept three of the four prizes at the Cannes Directors’ Fortnight for J’ai tué ma mère (I Killed My Mother).

The 20-year-old’s first feature won the Art Cinema Award, given by an international jury of independent cinema programmers, and the SACD Prize for best French-language film.

Dolan also won the Regards Jeunes 2009 Prize, given to a first film by a jury of young cinephiles.

The Montrealer wrote and directed the coming-of-age movie about a 16-year-old boy who discovers his gay sexuality and hates his mother.

Turned down by Telefilm Canada, Dolan made the film mostly with money he earned as a child actor. SODEC kicked in after shooting was complete.

The film’s distributor, Rezo Films, has reportedly sold Killed to Australia, Greece, Turkey, Korea, Russia and Albania.
