Review of British Intelligence

Terrific World War I set B-movie featuring a brilliant performance from Boris Karloff. Margaret Lindsay is the beautiful German spy sent undercover as a refugee to the home of a wealthy government official (wonderfully played by Holmes Herbert) in London , in the hope of stealing the plans for the locations of British munition wearhouses and locating the agent known only as Franz Strendler. Karloff, posing as a butler to Herbert, is also a spy and as the plot thickens, with genuine twists and tricks, it is only in the final scene that it is revealed who is actually working for who. Exciting biplane dogfights, thrilling zeppelin bombing scenes and more German agents than you can shake a stick at (even the bloody milkman is a spy) make this a very enjoyable film all round. Frederick Vogeding's German baron, whilst only appearing briefly at the start of the film, makes an impression too. Fun.
Could be seen as a companion piece to Powell's The Spy In Black as both are First World War thrillers, with Karloff's and Conrad Veidt's characters bearing similarites.
