Wikipedia lists screen adaptations of just one novel and three short stories by prolific Golden Age SF and fantasy writer Fritz Leiber.
Are there any other lesser-known adaptations of his work that are not listed there? Or have any of his works been optioned for possible movie or TV production?
Given Hollywood's newfound interest in big-budget fantasy movies and TV shows aimed at adults in the wake of the success of Lord of the Rings and Game of Thrones among others, it's hard to believe that nobody is working on making a movie or TV show out of the "Fafhrd and the Gray Mouser" books, which are among the undisputed classics of the swords-and-sorcery genre.
