This is truly a great Classic 1940's B&W film with a great cast of actors, George Raft,(Joe Barton),"Oceans' Eleven",'60, was a so called salesman and a spy who ran into all kinds of problems on a train with a woman and obtained war time maps and plans which the Nazi's and Russians wanted very desperately. Sydney Greenstreet,(Colonel Robinson)," Devotion",'46, worked for the Russians and wanted to get rid of Joe Barton in the worst way. Much to my surprise, Peter Lorre(Nikolai Zaleshoff),"Beat the Devil",'53, was a good spy for a change. Brenda Marshall,(Tamara Zaleshoff)," Constant Nymph",'43 gave a good supporting role and managed to her herself beaten up a few times. If you love Greenstreet, Raft & Lorre, this is a must see film!
