The Brighton Strangler is a 1945 American crime film directed by Max Nosseck and starring John Loder, June Duprez and Michael St. Angel. In Britain an actor goes mad and tries to live out the life of the character he is playing by committing a string of murders.
This rather daft 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.
