Knowing they needed someone to fulfill the small but pivotal role, Reynolds remembered Herbert Coward, a guy he once worked with at Ghost Town in the Sky theme park in North Carolina. Coward played a gunfighter there. Since parts of Deliverance were being filmed at the park, Reynolds recommended his old pal for the job, then helped him prepare his lines before filming.
[quote] Jon Voight Almost Plummeted Off A Cliff
Jon Voight wanted to make sure the perils faced in Deliverance were palpable for the audience. This quest for authenticity nearly caused him to plummet off a cliff. The actor told The Guardian he wanted a rock-climbing scene filmed in close-up, which would prevent the use of a stuntman.
"I was about 10 feet up on the face, which was slippery and almost perpendicular," he said. "I told the two grips below me: 'If I start to fall off, I’m going to push off the rocks. And you’ll catch me.' I started to slip, called out and one of them caught me."
The danger was worsened by the fact that a sharp rock was mere inches from the actor's head when he was caught.
[quote] Ronny Cox Dislocated His Shoulder On Purpose
One of the most difficult-to-watch scenes involves the discovery of Drew's body. His arm is twisted up around his head, which can make even the most steadfast viewer queasy. That effect was not achieved through make-up or prosthetics. It's Ronny Cox's real arm.
The actor told The Wrap he contracted a mild case of polio as a child. This left him with an ability to "do this thing where my shoulder comes out of place and just completely dislocates." During production, he mentioned this fact to Boorman, who thought it would be great for Drew's demise. Cox agreed, intentionally dislodging his shoulder for the sequence.
[quote] The Most Famous Line Of Dialogue Was Conceived By A Crew Member
When fans think of Deliverance, the words "squeal like a pig" probably come to mind. One of Bobby's tormentors mutters the line as he defiles the canoer. There have been various rumors about the source of that line. In the DVD audio commentary, John Boorman sets the record straight, attributing it to a crew member.
The director said the studio wanted him to shoot two versions of the scene, one with dialogue suitable for an eventual network television airing. Boorman didn't want two versions, though, so he tried to come up with something powerful but also profanity-free. When someone on set said "squeal like a pig," Boorman knew he had a winner.
[quote] Author James Dickey Cracked Four Of John Boorman's Teeth
Deliverance author James Dickey didn't really care for John Boorman as a director. Then again, the notoriously picky writer might not have been happy with anyone other than himself directing the film. At one point, his rage got the best of him and the writer resorted to physical aggression toward Boorman.
Dickey frequently clashed with the director over the movie's tone and staging. Tensions came to a head between them one night, and an inebriated Dickey struck Boorman in the face. Dickey's blow cracked four of Boorman's teeth.
Despite the tussle, Dickey still did his cameo as a sheriff.
[quote] The Actor Who Played 'Mountain Man' Attempted To Frighten Ned Beatty For Real
Actor Bill McKinney plays "Mountain Man," the hillbilly who violates Ned Beatty's character, Bobby. The scene is so jarring because of the sense of menace McKinney brings. It doesn't feel like a performance. There's a good reason for that: The actor took a Method approach to his role, attempting to frighten Ned Beatty off-camera.
In a group interview included on the 40th Anniversary Blu-ray, Burt Reynolds explained what happened:
[quote] I just remember McKinney would sit three tables away from us during lunch, just staring at Ned. Later I asked Bill why he was doing that. He said he was taught by Bruce Dern. And Bruce Dern said your main thrust, pardon the pun, should be to scare the hell out of Ned Beatty. And he did.
