The Strangler is a 1964 American psychological thriller film directed by Burt Topper and starring Victor Buono, David McLean, Davey Davison, and Ellen Corby, with a screenplay by Bill S. Ballinger. It follows a disturbed lab technician who embarks on a serial killing spree of young female victims. The film was inspired by the Boston Strangler, a serial killer who murdered several women in the 1960s, and went into production while police were still attempting to solve the crimes.

Plot

Leo Kroll is a mother-fixated lab technician who collects dolls. He is also a serial killer, responsible for the death of a number of nurses, and is questioned by the police regarding those murders, but is released. Kroll claims his next victim, Clara, the nurse who has been looking after his possessive mother, who is in hospital after a heart attack. However, he leaves a doll behind at the murder scene. (A subplot features Kroll becoming enamored of Tally, one of the girls who works at the amusement park stall from which he won this doll.)
