"Hunger", artist Steve McQueen's widely acclaimed directorial debut, also picked up three awards, followed by Mike Leigh's uncharacteristically upbeat "Happy-Go-Lucky", which took both the best supporting actor and actress prizes.

‘Slumdog Millionaire’ won the best British independent film, best director and most promising newcomer categories, the latter going to young actor Dev Patel who played the lead role of Jamal.

The movie has already won rave reviews at film festivals and generated early Oscars buzz.

Also with three awards was Hunger, a hard-hitting film about the final days of IRA prisoner and hunger striker Bobby Sands in 1981.

Sands was played by Michael Fassbender, who won the best actor category, while McQueen was awarded the Douglas Hickox prize for best debut director and cinematographer Sean Bobbitt was honoured for best technical achievement.

Best actress went to Vera Farmiga in "The Boy in the Striped Pyjamas", and the best screenplay award was won by Martin McDonagh for "In Bruges".

Alexis Zegerman was named best supporting actress for Happy-Go-Lucky, and Eddie Marsan won the best supporting actor prize for the same film.

"The Escapist" won the best achievement in production award, "Man on Wire" won best documentary, "Soft" won best British short film, and best foreign film went to "Waltz With Bashir", Ari Folman's haunting Middle East war animation.
