The Deer Hunter (1978)

Factual error: The boys go deer hunting somewhere in the Appalachians, but the geology is all wrong. That scene is in North Cascades National Park in Washington State. In addition, the "deer" they are hunting is a Red Stag. Not typically found in the Appalachians.

Continuity mistake: During the long wedding scene, while Michael watches Linda on the dance floor, the level of the beer in his glass goes up and down several times.

Factual error: When Michael Vronsky gets back from his tour he has a full grown beard. The only branch of the service that allows a beard is the Navy, and he was an Army Green Beret. The beard would only have been tolerated if Mike was either not in his Class A uniform or actively performing on a mission, neither of which are the case here. In addition, he's wearing a Black Beret, but his left shoulder patch is the 101st airborne, not Special Forces. Finally, he has six or seven hash marks on his right sleeve. Each hashtag is for 3 years of active duty service.

Trivia: To acquire the withdrawn, hollowed-out look of his character, Christopher Walken ate nothing but bananas and rice.

Trivia: Roy Scheider was originally cast as Steven but quit the production two weeks before filming began.

Trivia: During the helicopter stunt, the runners caught on the ropes of the suspension bridge and as the helicopter rose, it threatened to seriously injure both Robert De Niro and John Savage. The actors gestured and yelled furiously to the crew in the helicopter to warn them. Footage of this is included in the film.

Michael: You wanna play games? All right, I'll play your fucking games.

Michael: You okay?
Linda: Did you ever think life would turn out like this?
Michael: No.

Michael: A deer has to be taken with one shot. I try to tell people that but they don't listen.

Question: What does "mao" mean?

Question: What are the silver pins on Dinero's shoulders on his dress uniform?
