Hu-Man is a 1975 sci-fi film about an actor whose fate in dangerous situations is determined by the audience. The film has been described as a cross between The Running Man and Slaughterhouse Five, with an original score reportedly by psych-rock band Gong.
The reason for its lack of availability is unknown, but it's likely that a print exists since clips from the film were shown on a 1998 episode of the UK series Scene by Scene that profiled Stamp. However, that print's whereabouts are still unknown.
