Here is the BFI introduction to a groundbreaking 70s British movie:
Nighthawks is a richly authentic, pioneering account of gay life in the late 70s, told with refreshing honesty and humour. We follow a young teacher as he cruises in clubs and reveals a double life. With volunteer extras and privately raised money, the film was firmly rooted in the gay community of its day, and remains powerful and fascinating.
The film will be introduced by director Ron Peck.
Here (and above) is an extract.
