Dominic Savage's Out Of Control received the Michael Powell Award for Best British Film at the 56th Edinburgh International Film Festival which closed on Sunday with the British premiere of Christopher Nolan's thriller Insomnia.

Savage's improvised drama, that tells of a teenage boy whose life is made a living hell when he is sent to a young offenders institute, stars Tamzin Outhwaite and David Morrissey and is scheduled for UK television transmission next month.

It faced strong competition from Lynne Ramsay's Morvern Callar, Damien O'Donnell's Heartlands and Mike Leigh's All Or Nothing.

The Guardian New Director's Award went to Mexican director Carlos Reygadas for the hypnotic Japon, a critical favourite at Cannes earlier in the year. Previous winners include Alejandro Gonzalez Inarritu for Amores Perros and Zacharias Kunuk for Atanarjuat-The Fast Runner. Marius Holst received a special mention in this category for his atmospheric, shoestring chamber drama Dragonflies.

The Standard Life Audience Award was won by Rabbit Proof Fence. Phillip Noyce's moving drama unfolds in the 1930s and tells a true story of three young girls who are part of the stolen generation of Aboriginal children removed from their mothers and forcibly resettled with white families. It had led the poll from its first screenings at the Festival and was described by Artistic Director Shane Danielsen as "a great film and an important film."

Anna Jones's Sky High received the Saltire Society Grierson Award for Short Documentary. The McLaren Animation Award went to An Eye For An Eye. Joachim Trier's Procter won both the Kodak and Short Film Bureau Award for Best British Short Film and the Prix UIP for Best European Short Film and will now be eligible for the European Film Awards in Rome this December.
