On mysterious character appears to have two different-colored eyes. (You can check it out here.) That's not the case in real life, but there are many celebrities who have eyes with more than one distinct hue.'s series "Castle Rock," Bill Skarsgård's
The condition is called heterochromia iridis, and it's not that rare, according to the NIH (National Center for Advancing Translational Sciences). Sometimes this results in a portion of one eye having a different color, called sectorial heterochromia, or it can mean having two different-colored irises completely, aka complete heterochromia. It's often caused by abnormalities of the iris, but can also be present at birth.
From two actors in "Mission: Impossible — Fallout" to a few onscreen superheroes, here are the actors you may not have realized have different colored eyes.
Kate Bosworth is probably the most well-known actress for having two different colored eyes.
You may not have noticed Bosworth's different-colored eyes, because casting agents and directors had her wear colored contacts while filming to make her eyes appear one color.
In 2006's "Superman Returns," director Bryan Singer told her to ditch the lenses and go natural.
"One of the first things I had to do when I got to Australia was screen test for my eyes with the wig and the costume, just to see if Bryan wanted to keep them the way they are. And he decided that he wanted to," Bosworth told the Sydney Morning Herald. "So now the Lois Lane dolls have different colored eyes, which is strange."
Mila Kunis had two different colored eyes for years because of an injury causing blindness in an eye.
The two colors were more noticeable when Kunis was younger. She had a chronic inflammation of the iris, which made it difficult to see. A cataract that formed as a result made her eyes appear different colors. She later had surgery to correct it.
"I was blind in one eye for many years, and nobody knew," Kunis told Cosmopolitan in 2011.
"I had surgery a couple of months ago," she added. "They cut it open and dropped a new lens in there."
Superman actor Henry Cavill's eyes are mostly blue, but real fans know one of them has a tinge of brown.
It's not easy to see, but if you look at the star closely, he has a patch of brown in the top of his left eye.
"Star Trek" actress Alice Eve said it took an ex-boyfriend months to realize she had one hazel and one blue eye.
"One boyfriend, who soon wasn't my boyfriend, it took nine months to notice," Eve told Conan O'Brien in 2012 of an ex. "He was like, 'Do you have different colored eyes?' I was like, 'Are you joking? What have you been looking at?' Nine months in!"

Cumberbatch has sectoral heterochromia. His irises are a mix of blue and green.
"Star Wars" actor Simon Pegg revealed he has a bit of brown in one of his eyes on a UK show in 2008.
Pegg stumped the hosts of UK show "The Sunday Night Project" when he revealed he has sectoral heterochromia.
"My eyes are two tone. They're mostly blue-grey, but in my right eye I have a flash of brown," Pegg explained.
