Willem Dafoe will appear in James Wan’s “Aquaman,” the actor told The Guardian.

Dafoe who will play Vulko, a trusted advisor to Aquaman and Atlantean politician, will first appear as the character in next year’s “Justice League,” directed by Zack Snyder.

In an interview published on Thursday, the actor confirmed to The Guardian his involvement on “Aquaman.”

“‘Justice League’ is very particular because it’s an ensemble movie and my character is being introduced here in order to be a principal role in ‘Aquaman,'” he said. “These films are a different experience. They have different responsibilities, different resources and different intentions. It’s nice to go between those worlds if you can. They serve different impulses.”

Vulko might be familiar to DC Comics readers as an on-again, off-again confederate of Aquaman. Initially launched in the late ’60s (in “The Brave and the Bold” No. 73), Vulko began life as the chief scientific advisor to the throne of Atlantis.

Dafoe’s recent credits include “The Fault in Our Stars” and “John Wick.” He will next be seen in “The Great Wall,” costarring Matt Damon.
