Fox 21 and Hulu have teamed for a television series based on Hitman, the global best-selling video game from IO Interactive. A pilot script will be written by Derek Kolstad, creator and writer of the John Wick action film series who also penned the third one that will be released in 2019. Hitman has sold more than 25 million copies since being launched in 2000. It centers on Agent 47, a meticulous and lethal assassin with a mysterious backstory. The character has been the subject of two films released by Fox — 2007’s Hitman and 2015’s Hitman: Agent 47 — and the intention here is to hew closely to the mythology of the perennially popular video game.
