Wikipedia lists screen adaptations of [just one novel and three short stories](http://en.wikipedia.org/wiki/Fritz_Leiber#Screen_adaptations) 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.
