Val Guest was an English film director and screenwriter. Beginning as a writer of comedy films, he is best known for his work for Hammer, for whom he directed 14 films, and for his science fiction films. He enjoyed a long career in the film industry from the early 1930s until the early 1980s.

Hammer Film Productions Ltd. is a British film production company based in London. Founded in 1934, the company is best known for a series of Gothic horror and fantasy films made from the mid-1950s until the 1970s. Many of these involve classic horror characters such as Baron Victor Frankenstein, Count Dracula, and the Mummy, which Hammer reintroduced to audiences by filming them in vivid colour for the first time. Hammer also produced science fiction, thrillers, film noir and comedies, as well as, in later years, television series.
