Within the Woods is a 1978 horror short film written, directed and produced by Sam Raimi. Raimi drew inspiration from his earlier short film Clockwork, deciding to produce a "prototype" horror film to help build the interest of potential investors. Raimi cast his friends Bruce Campbell and Ellen Sandweiss as the two protagonists and produced the film for $1,600. Shot on location in a remote cabin in the woods, production was a difficult process because of the low budget. Several of the special effects presented in the film were done in a severely low budget manner, some of which were improvised on set. The film centers around demonic possession and mysterious forces originating from the woods.
