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.
A barber named Sweeney Todd slits the throats of his unsuspecting customers, robs them and then dumps their bodies down into his cellar through a trapdoor.
He and his partner in crime, Mrs. Lovett, cut up the bodies and use the pieces to make meat pies which she then sells in her bakery shop.
