When you watch the Band of Brothers episode that takes place during the Battle of the Bulge, you literally can feel the cold.
Thanks for mentioning it - I just requested the DVD from Netflix.
With the wisdom of hindsight, we can see, in these first reports about the Ardennes attack, the signs of Fail. For example, it’s reported that the Luftwaffe flew around 450 sorties in the first 24 hours of the attack, and lost over 140 planes.
Somewhere, I read an analysis that said that, when the first day’s objectives weren’t all achieved, there was virtually no chance of the attack’s turning the course of the war.
It was ingenious how they did the snow effect. It is mostly paper. The Bastogne scenes were shot partly indoors so it requires the actors' ability to communicate how cold it is. I learned all that from the bonus disk of the series that has segment called The Making of Band of Brothers.
Of all the Band of Brothers episodes, the Battle of the Bulge seen through the eyes of the combat medic was the one that disturbed me the most.
