Saving Private Ryan - Invisible Headshot
Just after the Americans take Omaha at the start, there is a scene where two US soldiers advance on a German bunker. Two German soldiers (a bald guy and one with a helmet) emerge with their hands up in surrender; one of them drops his MP-40. Then they start pleading in German, but the American soldiers cannot understand them:
"I'm sorry, I can't hear you..."
The two Americans kill them with simultaneous single rifle shots; you see a smoke puff on the left German's (the one with the helmet) chest, indicating this is where the bullet hit him. Watch his corpse as the two US soldiers speak.
"What did he say, what did he say?"
"Look, I washed for supper!"
The left dead German's helmet has fallen off and you can see a bloodied bullet-hole in his FOREHEAD.
