Hair?
I thought that this was pretty good film. But one detail bothered me. Did POWs receive gel products in German camps during WWII? Most of the British POWs in this film had large amounts of gel in their hair for styling. I find it hard to believe that they actually did. I know that it's a minor detail but details like that can make or break the feel of authenticity. After all, you don't (or shouldn't) want the actors in a war film to look like actors.
Film: 7/10
