The Wicker Man
This 1973 British horror film follows Sgt. Neil Howie (Edward Woodward), who has been sent to a British isle known for its pagan rituals in order to investigate the disappearance of a young girl. As it turns out, there is no missing girl, and the residents of the island lured the officer there to use him as a human sacrifice in their ceremony, where he is burned alive inside of a gigantic "wicker man" statue.
