Dark Intruder 1965 is a horror film made for TV that was released theatrically, and starring Leslie Nielsen, Mark Richman and Judi Meredith. The film is set in San Francisco in 1890 concerning playboy sleuth and occult expert Brett Kingsford Nielsen. This atmospheric blackandwhite film is only 59 minutes long, was directed by Harvey Hart, and was the pilot for a failed television series called The Black Cloak and was written by Barr Lyndon.
The film opens, after the murder of a woman in dark alley by a mysterious caped figure, on a scene between Kingsford and his fiance Eveleyn Lang Meredith. Kingsford is an expert on the supernatural and along with his dwarf assistant Nikola Charles Boldender he is called in by police to uncover the scheme of a Sumerian demon to return to earth and take over a human body. A series of murders of women similar to those committed in 1888 London by Jack the Ripper has taken place in San Francisco in the San Francisco killings, however, a series of statuettes carved of ivory and depicting a repulsive reptilian head is left beside each body. In each statue found at a victims feet, the demon in the little figurines emerges from the back of a man, budding out farther with each crime. It as though with each killing, the demon is freeing itself from its host a little bit more. There also seem to be connections between the various four victims.Kingsford initially consults an old Chinese curio dealer, Chi Zang Peter Brocco for advice. The dealer, whose shop has a statue of a multiarmed Chinese god who may be Yu Lueh shows Kingsford a mummified creature with a hideous fanged mouth which the priest claims is a Sumerian demon. The mummified demon is accompanied by a sevenspoked wheel. The priest says that the demon will commit seven killings, one for each spoke, until it accomplishes its purposes, according to mystic periods of time known only to itself. Kingsford picks up the small mummy but drops it when it becomes hot and leaves him with a scratched hand. ........
