5. The Wicker Man
A weird mystery thriller, this movie is about a sergeant who is sent to a Scottish island village to investigate the mysterious disappearance of a young girl, but soon finds out that the villagers claim she never existed. It gets weirder and weirder as he stumbles across the pagan-like rites that the town participates in, and he tries to figure out what exactly is going on. While made on a tiny budget, it has hit iconic cult-following status.
