Sweeney Todd is a 1928 British silent crime film directed by Walter West and starring Moore Marriott, Judd Green and Iris Darbyshire. It was adapted from a popular 1847 stage play by George Dibdin-Pitt called The String of Pearls, or The Fiend of Fleet Street, which in turn was based on an anonymous story called The String of Pearls: A Romance that was serialized in magazine format in 1846. This was the first time the story was adapted into a play, and it featured a surprise twist ending that doesn't appear in later stage versions of the Sweeney Todd legend. It was filmed entirely on set at Islington Studios.
