Long Pigs (2007)

A documentary by two desperate young filmmakers who stumble upon the ultimate subject, a 33 year old cannibalistic serial killer named Anthony McAllister, who has agreed to let them document every aspect of his horrifically violent life-style. Initially terrified, the filmmakers get to know Anthony as a person. They even begin to identify with his ecological and philosophical justifications for his cannibalistic lifestyle. It's only when they investigate further that the filmmakers begin to doubt Anthony's accounts of his past. Tensions noticeably rise as the filmmakers continue to confront Anthony on his conflicting stories and ever-changing philosophies. During an awkward interview, the filmmakers interview Merle, the father of a young girl who was abducted and never found. This abduction was Anthony's first child victim. Merle welcomes them into his home and gives them a heart-felt experience that even Anthony is touched by.
