I Made a Fool Out of Hitler (1970)

Following a failed sabotage operation during the German Occupation of Greece, Major Laurens, a valiant officer of the British Army, finds himself held captive by the Nazis. With his life hanging by a thread, the local Resistance movement turns to an unlikely saviour: Grigoris Tsavos, a timid travelling showman bearing an uncanny resemblance to von Ruben, a ruthless high-ranking SS officer. Despite his apprehension, Grigoris must pluck up the courage to lead a crucial mission to rescue the captured military man. The question remains, however: does the reluctant patriot have what it takes to rise to the challenge?
