As has been the case with most cinematic video game adaptations, the Hitman movies that have come out so far weren’t critically successful in theaters. The 2007 one, simply called Hitman, starred Timothy Olyphant as the main protagonist, who is officially known as Agent 47. The supporting cast included Dougray Scott, Robert Knepper and Olga Kurylenko, to name a few. Hitman managed to take in $100 million off a $24 million budget, but it was met with mostly negative reviews. Although a sequel had been planned, that was scrapped, and years later, 20th Century Fox released the reboot, Hitman: Agent 47. That movie saw Rupert Friend playing the bald assassin, and some of the other actors involved included Hannah Ware, Zachary Quinto and Ciaran Hinds. Just like its predecessor, the reboot made a decent amount of money at the box office, but was also negatively received by critics. Given that James Gunn said “a few years ago” in his tweet, it stands to reason his pitch was for the reboot years before the final premise was nailed down.
