The Brighton Strangler is a 1945 American crime film directed by Max Nosseck and starring John Loder, June Duprez and Michael St. Angel.
During The Blitz in wartime London, an actor suffers a concussion and believes himself to be the character he has most recently been playing - a vicious strangler with a hit list of potential victims.
This film has been championed since 2013 by the British movie podcast "Attaboy Clarence", (named after the final line in It's A Wonderful Life) in which the Strangler's reading of the word "Canterbury..." has become the podcast's catchphrase.
