The Muppets' Haunted House (aka "The Muppets' Haunted Hotel" and "Muppet Haunted Movie") had been mentioned in several press kits released by The Jim Henson Company during the 1990s, spending that time in development as a potential feature film. As early as 1996, Brian Henson mentioned in a panel discussion that ideas for a Muppet horror/monster movie were being talked about at the company. By 1998, a script was written by Dan Milano, now titled "The Muppets' Haunted Hotel."
