Film 4 would be a suitable distributor for the filmmaker's low-budget horror/thriller film. Film 4 distributes many genres, including horrors and thrillers, primarily in the UK which is appropriate for an independent, low-budget film. They have also distributed films worldwide and have experience distributing to the target 15-24 male demographic. While it may be risky for Film 4 due to the low budget, they could advertise the film on buses, billboards, YouTube recommendations, and streaming services like Netflix to build an audience if they had confidence in the film.
