Director William Wellman served in France during WWI with the Lafayette Flying Corp. He put this experience to good use in the 1927 WWI movie Wings, winner of Best Picture at the very first Academy Awards ceremony.
Wellman’s war movies bring war down to the human level. The 1949 movie Battleground tells the story of the Battle of Bulge from the point of view a company of the 101st Airborne. The men are moved around in the snow from unknown point to unknown point, trying to keep warm, scrounging for something to eat, hoping not to lose another friend. They don’t even know for sure what country they are in.
