We in the US have no doubt seen a number of the training films made for our troops in World War II. We might not know about the ones made for British troops. "The New Lot" is an example. It depicts a couple of new recruits going into the army and having to go through the usual training.
We in the 21st century are bound to view these movies differently, given the sorts of wars that we've seen waged since World War II. I guess that we can accept these, considering that the enemy in World War II was responsible the slaughter of twelve million people (it's always worth reminding people that there are NO good Nazis).
Anyway, worth seeing. The cast includes Peter Ustinov and Bernard Lee (M in the original James Bond movies).
