Deliverance (1972)

Revealing mistake: In a scene where the canoes are shooting the rapids through a sheer cliff you can clearly see a stuntman climbing out of the water onto the rock.

Revealing mistake: When the mountain man is grinning at Jon Voight tied to the tree, you can see that his "missing" front tooth is actually painted black.

Continuity mistake: Burt is lying at the bank with broken leg flesh dangling. Next shot different angle, not dangling, then dangling again.

Trivia: At the end of the film, the police officer advising Beatty and Voight to go away and not to come back is James Dickey, the screenwriter and author of the book the film is based on.

Trivia: Burt Reynolds broke his tailbone while going down the rapids.

Trivia: Actor Billy Redden (who portrayed the inbred hillbilly banjo player) actually could not play the banjo at all. Despite training for the film, Redden's hand movements simply weren't convincing, so a local musician was hired to hide behind Redden and portray the left-handed fingerplay in complex banjo-picking shots. We only see the briefest snippets of Redden handling the banjo with his own two hands; however, when the iconic "Dueling Banjos" scene reaches a fever pitch, the left hand seen working the banjo frets is that of the real musician hiding behind Redden.

Mountain Man: Now let's you just drop them pants.

Mountain Man: Looks like we got us a sow here instead of a boar.

Bobby: Which way we goin', this way or that way?
Lewis: I think downstream would be a good idea.

Question: What exactly happens to Ronny Cox? Does he get shot by the sniper, does he fall out of the canoe and drown, or does he commit suicide?
