Indeed, there is no shortage of debatable evidence and probable hoaxes when it comes to the subject of UFOs and aliens. Yet as with any cultural phenomenon, there are those prime examples that rise to the top to become forever cemented into our collective consciousness. One such artifact is a 17-minute black-and-white film that became so iconic it is merely, and famously known only as "Alien Autopsy." The film sequence purported to show government or military Medical Examiners performing an autopsy on an alien lifeform supposedly recovered along with debris from an equally famous event, the 1947 Roswell UFO crash. One could argue that the film has become more well-known than the incident upon which it was supposedly based. The first public screening of the film occurred on May 5, 1995, in a small theater at the Museum of London.
