The Last Warning is a 1928 American mystery film directed by Paul Leni, and starring Laura La Plante, Montagu Love, and Margaret Livingston. The Last Warning was also one of the very last silent films Universal made — except it was also released in a “part-talkie” version, with roughly sixty feet of sound scenes added (only a minute or two). Its plot follows a New York producer's attempt to re-stage a play five years after one of the original cast members was murdered in the theater. The film is based on the 1922 Broadway melodrama of the same name by Thomas F. Fallon, which in turn was based on the story House of Fear by Wadsworth Camp, the father of the writer Madeleine L'Engle.
