MURDER! (1930)
ALFRED HITCHCOCK
Plot
Herbert Marshall (in his first sound film) plays a gentleman and famous actor, Sir John Menier, who has second thoughts about the guilt of a young actress Diana Baring (Norah Baring), whom as a jury member he'd helped convict of murder. So, before she's to be executed for the crime, he works tirelessly to prove her innocence by finding the real guilty party. A memorable scene with Marshall thinking while shaving.
