Very Accurate - Decision Before Dawn. Great flick about use of turncoat German POWs for intelligence operations in latter days of the war. Filmed on location in Germany after the war.
Wildly Inaccurate - Battle of the Bulge looks like the hands down favorite, but how about Saving Private Ryan? I don’t think George Marshall ordered any Ranger op to exfil the last Ryan out of Normandy.
I think the last Ryan basically got a discharge letter, packed his bags and went home.
