I never watched it, Nom.  Just seemed too weird.

Not my cuppa.

Because the movie industry where they have no real morals and insist on putting a sex scene and blood splattering in every movie doesn't want to offend anyone.. Make sense?? Didn't think so...

It's a very odd and bizarre movie and I do not think it could be remade. It is exactly as it needs to be as it was filmed. A remake would ruin it. 

Because that part of the river is gone.They were going to dam it weren't they?

Even today when anyone plays that song on a banjo there is entire generation that starts laughing...for it's time it was quite progressive- in an odd way.  It's a classic & couldn't be made any better. and Viny is right, they'd turn the rape scene into a love/sex scene and there would be a lot more blood.- See it just wouldn't work.

The summer of 2003 my kids were 16, 15, and 13. I borrowed a lot of movies from the library (for free) that were older so they could see some of the movies I'd seen in my younger days. 
That fall, one of the eldest's teachers played music during class while the kids worked on assignments.  One day he played "Dueling Banjos".  

"I know that song!" exclaimed Andy. "No, you don't!" protested the teacher.
"Yes, I do," Andy insisted.  "It's from the movie with the scary hicks." 

(I would hope there would be no service in that area and those cell phones would be useless)
