The movie told the true story of a group of gay activists who work to help miners during their lengthy strike of the National Union of Mineworkers in the summer of 1984.

Accepting the top award, Pride director Matthew Warchus said: "We're getting reports from up and down the country of audiences standing up and applauding. That doesn't really happen in British cinemas. It's just extraordinary. It's a real tribute to the source material."

Writer Stephen Beresford said, "When I was first told the story I was blown away by it - people ask 'is that really true? It took 20 years to convince anyone that a film about vegan lesbian activists was a sure-fire hit."
