Marvel's Moon Knight TV series on Disney+ is becoming a star-studded affair. Oscar Isaac and May Calamawy were recently announced for the series, and now, Ethan Hawke will join the cast, according to The Hollywood Reporter. And Hawke will be in a dubious role for the upcoming show.

The actor has landed the role as the lead villain in the series. However, the name of the character he is playing is unknown at this time. While Moon Knight's villains range from the brainwashing Crossfire to Vietnam War vet Black Spectre, the hero's greatest villain is Raul Bushman--the former friend of Marc Spector (the man who would become Moon Knight), who went on a killing spree after discovering some gold. While Moon Knight debuted in 1975, the Bushman character debuted in Moon Knight #1 in 1980. At the time of this writing, there's no clear indication of who Hawke will play.

Isaac will be playing Spector/Moon Knight, a vigilante in white who suffers from multiple personalities and mental illness, and may have some sort of connection to Egyptian gods--depending on who is writing the character.
