question: What is the name of the character that is the banjo player in deliverance?
short_answers: Lonnie
context: In "Deliverance," a scene depicts Billy Redden playing it opposite Ronny Cox, who joins him on guitar. Redden plays "Lonnie," a mentally challenged and inbred but extremely gifted banjo player. Redden could not actually play the banjo and the director thought his hand movements looked unconvincing. A local musician, Mike Addis, was brought in to depict the movement of the boy's left hand. Addis hid behind Redden, with his left arm in Redden's shirt sleeve. Careful camera angles kept Addis out of frame and completed the illusion, though anyone familiar with bluegrass banjo playing can see that the left-hand movements do not match up with the music produced, and that the banjo being used (an open-back instrument) could never produce the music one hears (clearly from a resonator banjo). The music itself was dubbed in from the recording made by Weissberg and Mandell and was not played by the actors themselves.
