The Banjo That Delayed It All
When Luke is informed of his mother’s death, he sings the song “Plastic Jesus” while playing the banjo. Newman is really playing the banjo in the film. He didn’t know how to before the movie, but producers delayed filming of this scene so Newman had enough time to learn how to play it.
The Author’s Cameo
The author of the book the film was based on, Donn Pearce, surprisingly makes a cameo in the film. He makes a short appearance as the convict “Sailor.” Donn Pearce actually was kicked off the set towards the end of filming because he was violent. He punched someone and was then banned from the set and the movie premiere.
