The fates of the thousands of Nazis who escaped from Europe after the downfall of Hitler is one which has led to much speculation and more than a few conspiracy theories, not least the idea that Hitler himself may have escaped Germany himself and lived out his days hiding out in Latin America. Escaped Nazis form the basis for the classic 70s thriller Marathon Man, directed by John Schlesinger and starring Dustin Hoffman, Roy Scheider and Laurence Olivier. Featuring one of the most memorable torture scenes in movie history, in which Hoffman's character Babe Levy is given some uncompromising dental treatment by Olivier's Nazi war criminal trying to track down diamonds stolen from concentration camp inmates, Marathon Man is a quintessential 70s political thriller. If you're in the mood for another great Nazi war criminal conspiracy thriller you can't go wrong with 1978s The Boys From Brazil - this time Laurence Olivier switches sides and plays Ezra Lieberman, a Nazi Hunter tracking down Dr Joseph Mengeles (Gregory Peck) in Paraguay.
