Marvel‘s Disney+ limited series “Moon Knight” series has landed its first actor in a villain role. The Hollywood Reporter has revealed veteran actor Ethan Hawke will play the series villain, however, Marvel’s not disclosing what exactly his role will be. There are seemingly two strong possibilities here as the outlet teases Raoul Bushman as an option, but there is Moon Knight’s brother Randall Spector, aka Shadow Knight, that is just as likely as he also has supernatural powers.
