Although Willem Dafoe will play a prominent role as Nuidis Vulko in Aquaman, fans will undoubtedly notice his character doesn't appear in Justice League, contrary to Warner Bros.' announcement last year. It turns out there's a simple explanation for that.

"There just wasn't enough time in this movie," said star Jason Momoa.

According to Gamespot, early versions of Justice League saw Aquaman spend more time beneath the waves, where Vulko would've served as the character's guide to his heritage.

"Vulko's his connection to Atlantis," Momoa said. "I think what Zack [Snyder] and I did, we were kind of trying to establish that he was taken down there as a boy, and he was an outcast, he was a half-breed, and he was built up as a young boy, because he was fed all these ideas by Vulko -- that he was the rightful king. And he gets down there, and he's a half breed, he's impure, and I'm just made to feel like I'm this disease. So after that, I was like, 'fuck you, fuck you, I'm on my own.'"

In theaters now, Justice League stars Ben Affleck as Batman, Gal Gadot as Wonder Woman, Henry Cavill as Superman, Amy Adams as Lois Lane, Jason Momoa as Aquaman, Ezra Miller as The Flash, Ray Fisher as Cyborg, Jeremy Irons as Alfred Pennyworth, Diane Lane as Martha Kent, Ciarán Hinds as Steppenwolf, Jesse Eisenberg as Lex Luthor and J.K.
