An actor-manager sitting on the jury for the murder trial of actress Diana Baring becomes convinced of her innocence after she has been convicted and sentenced to hang: he works to uncover the real murderer before sentence is carried out.
While filming Murder!, Hitchcock simultaneously filmed a German version, using a scenario written (from Dane and Simpson's novel) by British-born German script-writer Herbert Juttke and his Austrian co-writer Georg C. Klaren.
The German-language film was shot simultaneously on the same set as Murder!, but with German actors. The primary roles were taken by the following actors:
Alfred Abel (Sir John Menier)
Olga Tschechowa (Mary)
Paul Graetz (Bobby Brown)
Hermine Sterler (Miss Miller)
Ekkehard Arendt (Handel Fane).
The film was released, also by British International Pictures, in 1931 as Mary, with the Austrian/Belgian title Der Prozeß Baring.
