Kerouac also wrote a screenplay adaptation of the novel entitled "Doctor Sax and the Great World Snake". It was never filmed, but in 1998, Kerouac's nephew Jim Sampas discovered the text in Kerouac's archives. He proceeded to produce the piece in audio form, much like a radio drama, and release it in 2003 from his independent record label, Gallery Six (named for the site of the famous Six Gallery reading), in a partnership with Mitch Winston's record label, Kid Lightning Enterprises. The release consisted of two CDs and a book containing the screenplay with illustrations by Richard Sala.
