Berlin Express may not have much of a reputation, but it's one of Jacques Tourneur's best thrillers. Virtually none of it takes place on the Berlin Express, with the majority of the film shot on location in the awe-inspiring ruins of an almost totally destroyed post-war Frankfurt where Robert Ryan teams up with an Allies-in-microcosm group of companions including unflatteringly shot Frenchwoman Merle Oberon (sporting the film's worst accent by far) and Brit Robert Coote (who thankfully doesn't even attempt a Liverpool accent) to find Paul Lukas' kidnapped politician and save him from die-hard Nazi fanatics. Great moments abound, from the Paris opening where a carrier pigeon is shot, then nearly given a formal burial in the shadow of Montmatre's Sacre Couer by children before reaching maman's kitchen table to reveal a coded message, to Robert Ryan literally finding himself trapped in a barrel in bombed out brewery.
Great production line entertainment that demonstrates just how good studio product could be when you got the formula right, this is a trip well worth taking.
