The star of classic 1970s slasher film Black Christmas is returning for a new fan-made sequel. Released in 1974, Bob Clark's Black Christmas told the chilling story of sorority sisters being stalked by a mysterious killer over the Christmas holiday. Regarded as one of the very first true slasher films, the low-budget Canadian production was unique among horror movies for never receiving an official sequel. The only Black Christmas follow-ups to reach the screen are a pair of remakes, one in 2006 and another in 2019, and a 2019 short film, centered on the granddaughter of the original movie’s final girl, entitled It’s Me, Billy.
