The free event, which including food, drink and music from the era, features a reception before the showing of the 1946 thriller starring Humphrey Bogart and Lauren Bacall.
Film students Josh Moulinié, from the Forest of Dean, and Natalie Featherstone are part of the team organizing the screening which takes place on May 9 from noon.
She said: “It promises to be a great afternoon to enjoy with friends or even to meet new people. You can dress to impress if you prefer, but it’s not compulsory. There’s also a raffle and the proceeds will be raising funds for the Gloucestershire branch of the Age UK charity, which promotes social and interactive activities for the elderly to battle loneliness and isolation.”
