10 Alternate Endings To 2020 Movies You Almost Saw

10. Jon Hamm's Mister Sinister Arrives - The New Mutants

The New Mutants was undeniably one of 2020's most troubled releases, spending almost three years in production limbo before finally hitting cinemas last summer.

Yet in March 2018, just six months after the film wrapped, reports emerged that a planned post-credits scene had been scrapped, which would've introduced the antagonist Mister Sinister, as played by Jon Hamm.

Apparently all the material leading up to Hamm's reveal had been shot, though not the actual cameo by the actor himself, which was clearly intended to set up further films in the continuity.

Ultimately this was nixed, and Fox decided to replace Hamm's Mister Sinister with a cameo from Antonio Banderas as Sunspot's (Henry Zaga) father Emmanuel da Costa.

However, the Disney-Fox merger meant that none of the planned reshoots, including Banderas' cameo, ever took place, and so the film was eventually released with no post-credits scenes or A-lister cameos to speak of.

As perfect casting as Hamm might've been for Nathaniel Essex, given that The New Mutants was the death knell for Fox's X-Men continuity, it's just as well that the movie didn't tease something that would never be followed upon.
