- Saved from Development Hell: The book was originally going to be adapted in 1983. The rights then changed hands in 1984 when the author, Walter Tevis, died. Finally, in 1992, Scottish screenwriter Allan Shiach (who writes under the pseudonym Allan Scott) acquired the rights and wanted to make an art house film adaption. Then, in 2007 and 2008, Shiach started working with Heath Ledger to adapt the film...and then Ledger died. Finally, in March 2019, Netflix ordered a seven-episode mini-series adaptation. All in all, it took Shiach twenty-eight years after he acquired the rights to make an adaptation.
