Tony Award-winning director Warchus (Matilda: The Musical, God of Carnage, The Norman Conquests) directs the 1984-set film, which stars Bill Nighy, Imelda Staunton, Dominic West, Paddy Considine, Joseph Gilgun, Ben Schnetzer and George MacKay.
The screenplay was written by playwright Stephen Beresford (The Last of the Haussmans).
"Pride" will be screened as the closing film in the Directors' Fortnight series.
Here's how it is characterized: "It’s the summer of 1984 – Margaret Thatcher is in power and the National Union of Mineworkers (NUM) is on strike. At the Gay Pride March in London, a group of gay and lesbian activists decides to raise money to support the families of the striking miners. But there is a problem. The Union seems embarrassed to receive their support. But the activists are not deterred. They decide to ignore the Union and go direct to the miners. They identify a mining village in deepest Wales and set off in a mini bus to make their donation in person. And so begins the extraordinary story of two seemingly alien communities who form a surprising and ultimately triumphant partnership."
The film is produced by David Livingstone for Proud Films and executive-produced by Pathé’s Cameron McCracken and BBC Films’ Christine Langan. Natascha Wharton is lead executive producer for the BFI Film Fund.
