For all of the talk of superheroes and monsters in the first three MCU movies, they were fairly well grounded. They were all set on Earth and grounded in science, for a start. It wasn't until Thor came along in 2011 that that all changed.
Hiring Kenneth Branagh, with his background in theatre, was a masterstroke. He perfectly balanced the theatricality of Asgard without doing a disservice to the material by trying to make it too "normal". Instead, we got a blend of Shakespeare and comic books and it might well be one of the most underrated movies in the MCU.
And as we continue to look ahead to Endgame, we're looking back and to the skies for Thor's debut...
10. Kevin Feige Regrets Thor's Eyebrows
Over the years, there have been lots of things Marvel Studios have regretted. They're got a rich history of dropping storylines and characters or just blatantly retconning the bits they didn't like. When you have their sort of power, you can do that. You can do whatever you want, frankly.
The biggest disparity between size of mistake and feelings of regret is courtesy of Thor, too, as Kevin Feige admitted to Uproxx years after the film's mistake that one thing they did still really grates. Apparently, the decision to dye Chris Hemsworth's eyebrows the colour of sunshine to match his hair is one of Feige's big regrets:
“I’ll tell you one specific example I just thought of today and I laugh at it. Definitively, the one thing I would definitely do differently if I had to do it over again, is we would not have dyed Chris Hemsworth’s eyebrows blonde in the first Thor. Because we were like, Thor is blonde! He has to be blonde! And Hemsworth was great and awesome and pulled it off, but there are a couple of shots I watch and I’m like, oh my God, that poor guy, we made him freaking dye his eyebrows! That’s ridiculous! And I can laugh about it now because Hemsworth is Thor and he doesn’t need long hair, or a cape, or a hammer, or two eyeballs to be Thor.”
To be fair, if that's your only real regret, you're clearly doing something right.
