Being an MCU Stan usually means you go on and on about all the great talent Disney hires, even though you've barely seen anything else they've made. Sure, occasionally you'll get someone like Taika Waititi or Sam Raimi who has made a widely recognized film before, but for the most part and for some reason, Disney tends to hire little known indie directors to oversee a process largely accomplished in boardrooms.
But if you're someone who actually does watch other movies, maybe you've seen some of these ones directed by people who have also worked the MCU. They're ordered by when the director's first MCU movie released, so they start with Jon Favreau and go on from there. Only officially hired directors as of October 2021 are included.
