Haunted Strangler Trivia:

Original Working Title:

 

Stranglehold. The film's 1956 screenplay had been written especially for Boris Karloff by b-grade mystery hack Jack Reed. The script eventually made it to the screen in 1959 under the title Grip of the Strangler.

 

Production Company:

 

Amalgamated. The company was set up in England by producer Richard Gordon specifically to develop Reed's Stranglehold script. Financial support for the project was provided by MGM, which is why The Haunted Strangler is often regarded as a British/American co-production.

Opening Night:

Grip of the Strangler opened in Picardilly Circus as a sole feature (unsual for the times), suggesting some degree of prestige and fanfare. The location may explain the movie's two exceptional cancan scenes: Picardilly was one of the traditional homes of the British cancan. Certainly, the costumes worn by Strangler's chorus girls hark back to the 1950s glory days of London's favourite music halls. 

The film was eventually released in the US under its more familiar title, The Haunted Strangler.
