In my basic head I always assumed animated stuff could be done much easier and quicker than live action, but I guess it takes a village of competent people.The animated stuff is in a weird area. I heard from coworkers that they were still doing storyboard work on season 1. I couldn’t get more information on whether it was for preproduction or post production in the form of retakes. It’s also traditionally animated and not 3D like What If? was (unless things changed…) which takes more time.
To be honest though, animation at Marvel is so poorly run because it’s not being produced by people who work in animation and so everything is just a bit… off. They hire actual comic artists to do design work but then they can’t understand how to make a character model sheet that actually works. It’s all very backwards.
