Ethan Hawke has made his Marvel.

Making his comic book adaptation and superhero debut, Hawke has closed a deal to join Oscar Isaac in Moon Knight, Marvel Studios’ series for Disney+, sources tell The Hollywood Reporter. 

Hawke will play the series’ lead villain.

Isaac is toplining the show, which is aiming for a March production start in Budapest.

May Calamawy, who is perhaps best known for her work in Hulu's Ramy, is already on the roll call.

Moon Knight has had several incarnations over the decades since his debut in 1975, from being an ex-Marine turned mercenary with multiple alter egos to being a conduit for the Egyptian moon god Khonshu, to, most recently, a dapper consultant. In the modern comics era, one them of the story has been the character's struggle with multiple personality disorder.

It is unclear who Hawke would play, but Moon Knight's archnemesis is a villain named Bushman, a fellow mercenary who turned on the hero when Egyptian gold came into the picture.

Mohamed Diab, the Egyptian helmer behind Middle Eastern drama Clash,  and Justin Benson and Aaron Moorhead, the indie filmmaking team behind sci-fi horror movies The Endless and Synchronic, are directing the show.

Hawke’s career began in the mid-1980s with teen sci-fi movie Explorers, but in the 35-plus years since, he has avoided the comic book movie genre. He has, however, starred in genre works, helping launch hit horror franchises Sinister and The Purge.

His wide-ranging work has seen him twice nominated for an acting Oscar (2002’s Training Day and 2015’s Boyhood) and twice for writing (2005’s Before Sunrise and 2014’s Before Midnight).

He recently wrapped The Northman, a Viking revenge saga from Robert Eggers that stars Anya Taylor-Joy, and is coming off of strong notices for The Good Lord Bird, a historical drama he created and starred in.

Hawke is repped by CAA and MGMT.
