Within the Woods is an 1978 horror short film written, directed and produced by Sam Raimi. Raimi drew inspiration from his earlier short film Clockwork, deciding to produce a proof of concept 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.
