All Quiet, Paths of Glory, La Grande Illusion, of course! What was I thinking of... Must be this medium and the thinking on one's feet at the end of the day it demands. Szabo's Hanussen springs to mind too.

Somebody should mount a major season of WW1 films. The (European) anniversary comes around next year. I'm sure there'll be lots of grim TV documentaries!

Thanks for reminding me of these great films.
