Preston's autobiography was the topic of a biopic movie reported to be under development. Nicolas Cage reportedly was to play Preston's character in the movie.
According to his co-author and agent, Greg Dinkin, he had been working with producer Norm Golightly, Nicolas Cage's former partner at Saturn Films, to develop a film that Academy Award winner Milos Foreman would direct, Cage would star in, and Saturn Films would produce on Slims Life.
"Just as we were about to finalize the movie deal, in August 2003, Slim was indicted on charges of indecency with his 12-year-old granddaughter. The film, the endorsement deals, and the appearance fees that would have earned him millions were replaced by legal fees, headaches, and heartbreak."
