Moonrunners is a great little film and surely deserves a modern release! Though it could have used a little tightening up in the editing department, it's still a well done, low-budget '70s film.
The only two characters to come straight across from movie to TV show were 'Uncle' Jesse Hagg, Sheriff Rosco Coltrane and "Cooter". Though, Cooter was not the neighborhood mechanic.
"Jake Rainey" was the Boss Hogg character.
Bobby Lee and Grady were the Hagg cousins,
"Zeebo" was a turncoat character never to be seen again.

Jerry Rushing himself had a role as one of Jake Rainey's bodyguards in the film, though it was a non-speaking role.
