"Deliverance" fits a lot of the clues. Would also work for a flume. Lol
For all you kids.

I just watched that movie last night! I love that movie!
I have a story to do with that movie,
My cousin Kramer and I were out one night, and after we went to a festival, we were just beat. We went to all places, a bar at a Holiday Inn.
There was a country string band playing, and we got our beers, and sat between the bar and the band.
The band, for some reason, starting playing "Dueling Banjos" and Kramer and I were extolling to each other our love of the movie "Deliverance".
I conjectured that the most manly man of the film was not Burt Reynolds, but Ned Beatty, because it took a lot of nerve for him to show his bum-
But instead of the word 'bum" the truth was we were saying "Great, big, white, fat a**"- and both Kramer and I were talking to each other as such-
"He read the script, saw that part, and decided he had it in him to show his 'bum."
"Yeh, he knew everyone was going to see his "Bum", but he went ahead and did it."
"Yeh! That takes nerves of steel to know the whole nation is going to see your 'bum- And! squeal like a pig! That's the most daring part in the movie."
And we thought about getting another beer. I looked over at the bar, and the friendliest, most most pleasant looking fellow lifted his mug and smiled at us.
We lifted our glasses and smiled at him.
"Kramer. That's Ned Beatty."
"(Gasp!) And we're sitting here talking about his 'bum'!"
We .... decided not to meet him. He pretty much knew we were fans from over there.
