I guess this movie is supposed to be romantic and cute. Kate Winslet was cute with the glasses? WWII code breaking is a fascinating subject and could have been interesting. Like the movie Pearl Harbor was turned into a soup opera and was awful so was this film. Of course the Polish code breaker becomes a traitor and gives the codes or code machine to the Germans because he is angry the Soviets slaughtered the Poles at Katyn. So the Polish guy helps the Germans? For one thing the due credit was not given in this film to the Polish cryptanalysis on which subsequent British codebreaking was dependent for its successes. The film was financed by Mick Jagger and Lorne Michaels of SNL. Why? Thanks Mick. The Poles laid the foundations for British success in cracking German codes and they get portrayed as traitors in silly soap opera movies like this. Yes it is fiction but unfortunately probly most of the world will learn about WWII code-breaking from this film.
