Marvel Studios has been the very model of a modern mini studio. Chief creative officer Kevin Feige and his small stable of executives have reliably delivered an unbroken string of global blockbusters to theaters and, starting in 2021, smash TV shows for Disney+. And they’ve done so while keeping virtually all their behind-the-scenes drama from spilling over into public view. It took just a week for that impeccable reputation to all but collapse, when Disney, Marvel’s parent company, fired Feige’s most high-profile lieutenant, Victoria Alonso, after 17 years with the company, most recently as the president of physical, postproduction, visual effects and animation.
