Creepy Green Light
Paranormal Adept
Maybe I'm late to the party on this one, but Netflix has a series called "History's Greatest Hoaxes" and one of the episodes dives deep into the Alien Autopsy. They interview the players involved and go to the location in England where it was filmed, how they filmed it, how they made the alien, how they had to dispose of the alien, etc. I'd recommend seeing it if you haven't already
