Sabotage (1936)
PG 76 mins

A ring of saboteurs is causing havoc in London with a series of explosive terrorist attacks. Karl Verloc (Oscar Homolka) is part of the group, but he maintains a cover as the kindly owner of a West End cinema, living contently with his wife in the suburbs.
But Mrs. Verloc (Sylvia Sidney) is beginning to suspect something – as is Scotland Yard Detective Sgt. Ted Spencer (John Loder) – and it isn’t long until Verloc’s deceit begins to impact his relationships – and threatens his wife's young brother’s life.
