Final Curtain is a 1947 novel by Ngaio Marsh, which was adapted for television in 1993 as part of the Inspector Alleyn Mysteries.
Final Curtain was a television pilot written and directed by Ed Wood in 1957. It starred Duke Moore as an actor wandering an empty theater after dark, where he is haunted by creepy sounds and eerie sights. The film is narrated by Dudley Manlove. Both Moore and Manlove also appear in Wood's cult film Plan 9 from Outer Space. Wood had hoped to use the film as the pilot for a television series he intended to produce called Portraits of Terror.
Scenes where an actor explores a theater were reused in Wood's later film, Night of the Ghouls, with a voiceover to make it fit in with the rest of the story.
Final Curtain was widely believed to be a lost film until a copy was tracked down and recovered by Jason Insalaco, great-nephew of actor Paul Marco who had appeared in several Ed Wood projects. The restored film was premiered at the Slamdance Film Festival on January 23, 2012.
