If you noticed a Jack Kirby influence in Marvel Studios' Thor: Ragnarok, you'd be unsurprised to hear it was definitely a deliberate move on the part of director Taika Waititi.

In this clip from the commentary track of the Thor: Ragnarok home release -- during Thor's arrival on Sakaar- Waititi explains that he's been a Kirby fan since his youth, and that, "Through this entire world, there's all this Kirby art everywhere."

"It made me really happy to be bringing his spirit and his designs into the film," Waititi said in the clip. "I've been a huge fan of his since I was a kid. Not only the shapes, but the colors as well. These vibrant colors, and cool, amazing strong lines, and bold colors."

CBR also has a look at concept designs for the Grandmaster's guards on Sakaar, which share a clear Kirby influence.

Based on Norse mythology, Thor is one of the many classic Marvel characters co-created by Kirby, along with Captain America, Iron Man, Black Panther, the X-Men, the Hulk, the Fantastic Four and many others. Kirby also co-created Hela, the main antagonist of Thor: Ragnarok, played by Cate Blanchett.

The 17th film in the Marvel Cinematic Universe, Thor: Ragnarok debuted in theaters last November, and grossed more than $850 million worldwide. It's currently available on home release -- with the considerably charming Waititi's commentary track -- digitally, and will be available on 4K Ultra HD and Blu-ray on March 6.
