John Wick director Chad Stahelski is developing an adaptation of the Spellslinger series. A highly influential figure in the action genre, Stahelski served as Keanu Reeves’ stunt double in The Matrix and later directed him in all four John Wick movies. As the status of John Wick 5 remains uncertain, Stahelski has several projects in the works which he will either produce or direct, including the John Wick: Under the High Table TV series, Highlander remake, Rainbow Six, Ghost of Tsushima, Black Samurai, and Shibumi.
