I don’t think I know many other actors who have been in as many war movies as British actor John Mills. Especially during the 50s and 60s he was in a large amount of British war movies. I was quite surprised when I realized how many I’ve seen.
Personally I liked him best – so far – in Ice Cold in Alex and The Colditz Story. But he is also great in many others like Above Us the Waves, In Which We Serve, The Way to the Stars and Dunkirk. I could go on and on.
