Alfred Hitchcocks second all-talkie thriller, Murder stars Herbert Marshall as pompous actor-manager Sir John Menier, a send-up of George DuMaurier. Summoned for jury duty, Sir John is one of 12 people who must decide the fate of Diana Baring (Norah Baring), a young actress on trial for murder. Though the girl is found guilty, Sir John believes that shes innocent and sets about to prove it on his own, exercising his actors prerogative of adopting clever disguises in the course of his investigation. Along the way, he is obliged to entertain a pair of lower-class clods, Ted and Dulcie Markham (Edward Chapman and Phyllis Konstam), who help him stage an elaborate re-enactment of the crime. Based on Enter Sir John, a novel and play by Clemence Dane and Helen Simpson, Murder was simultaneously filmed in a German version, with Alfred Abel replacing Herbert Marshall. ~ Hal Erickson, All Movie Guide
