As both the X-Men and the Fantastic Four are ushered into the Marvel Cinematic Universe, a whole new crop of yet-to-be-seen characters find themselves in need of a performer like Hamm to take the reins. More than willing to lend his talents to the world of the MCU, a wide breadth of possible characters soon to enter the MCU would be perfect for Jon Hamm, especially considering his impressive range as an actor. Shedding some light upon the situation, Hamm spoke to Screen Rant in an interview regarding his love for comic books, having been a longtime fan of Marvel since his childhood. Though Sinister's name was teased at the end of The New Mutants as a possible looming big bad, three years later the Fox continuity of the X-Men would officially end, putting the ball in Marvel Studios' court and robbing Hamm of his chance.

Once upon a time, conversations circled the superhero movie landscape regarding Jon Hamm playing Mister Sinister, a classic X-Men villain that Fox's films, shockingly, never explored. While the MCU might have many famous actors in its fold already, Jon Hamm is one Hollywood star who could fit in a wide variety of unfulfilled roles. Spoilers ahead for X-Men Blue: Origins 1.
