Recently resurfaced Thor concept art imagines Grey's Anatomy actor Kevin McKidd as the Marvel hero. Since his debut in his 2011 solo film, Thor has become a vital part of the Marvel Cinematic Universe. Though the second film in his standalone series, Thor: The Dark World, was a critical disappointment, he bounced back with Thor: Ragnarok. It provided a lighter take on the character and segued into his relationship with the similarly eccentric Guardians of the Galaxy. Now, it's hard to imagine anyone but Chris Hemsworth in the role, as he's navigated Thor's character development with ease. However, Hemsworth wasn't the only actor up for the role.

At one point, McKidd was reportedly in the running for Thor. This was back in 2008, around the time McKidd joined Grey's Anatomy as Owen Hunt. Though he didn't wind up getting the part of Thor, McKidd did eventually play a god, starring in Percy Jackson & the Olympians: The Lightning Thief as Poseidon only a couple years later. Another actor who nearly played Thor is Daniel Craig, who wasn't able to because of his role as James Bond. Other actors considered include Channing Tatum, Charlie Hunnam, and even Liam Hemsworth.

Because so many actors were up for the role, it makes sense early concept art varied. Marvel Studios Visual Development co-founder Charlie Wen shared some Thor concept art on Instagram today, which was based on McKidd. The art was previously featured in The Art of Thor, a Marvel artbook released in 2011. Check it out below:

It makes sense Wen specifies the art was based on McKidd rather than being a carbon copy. It only loosely looks like the actor, especially ten plus years after it was created. However, it does give a good idea of what McKidd might have looked like then with Thor's trademark long locks. Though McKidd didn't end up getting the Thor gig, it's not as though his career has tanked since. He's remained a fixture in the entertainment industry thanks to his ongoing Grey's Anatomy role. At this point, he's even outlasted several original cast members.

All told, the Thor concept art offers a fascinating reminder of the complicated design process for superhero films. Not only do artists have to create a look for the character, they also have to take into consideration whichever actors are up for the role. Though it's interesting to see the basis for what McKidd might have looked like as Thor, it feels like the right person wound up with the role.
