13 Ghosts (1960)

 

From Wiki- The occultist Dr. Plato Zorba bequeaths a large house to his impoverished nephew Cyrus. Along with his wife Hilda, teen daughter Medea and adolescent son, Buck, Cyrus is informed by lawyer Ben Rush that the house comes with ghosts that Dr. Zorba has collected from around the world. The will stipulates that the family must stay in the house and cannot sell it, or it will be turned over to the state. The family is shocked to find that the house is really haunted by 12 ghosts. The furnished mansion also comes with a creepy housekeeper, Elaine, who conducts seances, and a hidden fortune concealed somewhere on the property.

This is an enjoyable little horror-comedy movie.   William Castle is a great promoter, and a decent director.  The cast is good, though the star really is Margaret Hamilton, who plays Elaine Zacharides, the maid.  She may or may not be a witch.  Elaine is the only one who knows what is going on in the house (and the movie).  Her last scene is a classic.  I think a podcast about her is due now!
