Actor Oscar Isaac will join the Marvel Cinematic Universe as the vigilante Moon Knight, Marvel Studios confirmed today in a tweet. If you're sitting here thinking that you already knew this, you're not alone.

Before we get into the history behind this announcement, the tweet itself says "WE ARE MOONKNIGHT," which seems to nod to main character Marc Spector having multiple personalities that develop after Egyptian moon deity Khonshu comes to inhabit his body.

Marvel Studios announced the project in August 2019, and news broke in October 2020 that Isaac was in talks to step into the Moon Knight's white tights. Then, on January 8, 2021, newly-announced Moon Knight director Aaron Moorhead tweeted that "we're directing Oscar Isaac in a Marvel show."
