review for British Intelligence on AllMovie

While twiddling his thumbs waiting for horror films to make their eagerly anticipated comeback, Boris Karloff plays a German spy masquerading as a French servant masquerading as a British counter-espionage agent masquerading as a German spy, etc., etc. Or is it the other way around? Meanwhile, leading lady Margaret Lindsay does him one better by playing a British intelligence officer masquerading as a German spy masquerading as a British counter-intelligence officer masquerading as a German spy. Confused? Well, British Intelligence, if nothing else, proves that the English Secret Service was almost as dense -- but only almost -- as its German counterpart during World War I. Or is it World War II? With all the veiled references to a certain Herr Hitler, it is hard to pinpoint which. All of which add up to perhaps Karloff's most tedious Warner Bros. vehicle.
