Scared to Death (1946)

Dr. Josef Van Ee (George Zucco) runs a private mental institution where he and his son, Ward (Roland Varno), are keeping his daughter-in-law, Laura (Molly Lamont), against her will. Laura is convinced her husband is trying to scare her away from their marriage, while Ward assures her she needs the help he's offering. Things go from bad to worse when Van Ee's brother, the magician professor Leonide (Bela Lugosi), shows up with his dwarf partner, Indigo (Angelo Rossitto).
