The Owls' Nest

Here's the "dueling banjos" scene from Deliverance.

 The "banjo boy" was a young actor named Billy Redden -- but he's not playing the banjo; that's done by Ronnie Cox, the actor who's playing the guitar. Redden was neither autistic nor slow-witted. He was paid $500 for his appearance in Deliverance, and he's recently been working in a WalMart in Georgia.
