A some names have been added to every Marvel Studios movie since the first, Iron Manin 2008. Kevin Feige is the one that most people know. Louis D’Esposito is another, and a third is Victoria Alonso. Together, these three producers have worked together to build Marvel Studios in a historical juggernaut. However, in a shocking turn of events, Alonso has now left the company.

The Hollywood Reporter broke the news of Alonso’s exit, and that’s huge news for the superhero studio. Alonso has produced every Marvel Studios movie and show since inception. Her most recent title was President of Physical Production and Post-Production, Visual Effects and Animation at Marvel Studios, which is a fancy way of saying she was in charge of everything that happened when people were making the movies. And yet, since last week, she is gone.

io9 has contacted Marvel to see if there is any statement or reasoning behind Alonso’s departure will update this post when or if we hear back. But it is interesting that she has a memoir coming out in a few weeks called Possibility is your superpower, who will tell his story of growing up in Argentina until being one of the greatest architects of one of the Hollywood’s biggest brands. (I, for a, I am now even more interested in reading itjust in case she explains why she made that massive move.)

It is also interesting that this happens after the disappointing exit of Ant-Man and the Wasp: Quantumania, arguably the first real sign that Marvel movies might not be the instant, guaranteed mega-hits they’ve been for over a decade. So this is going to be intriguing to find out in the coming days if Alonso’s exit really signals a period of uncertainty within the company or if the timing was a coincidence. Either way, Marvel Studios as it is today, and has been, doesn’t become so without Victoria Alonso. It’s a huge loss for Marvel and a huge gain for whatever it does next.
