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."

　　I still can't quite wake up from this dream I'm having, that we're directing Oscar Isaac in a Marvel show. It's really happening.

　　In March, Oscar Isaac's production company posted a video of himself doing combat training. While it's possible that he could be training for the Metal Gear Solid film he's also starring in, the Instagram post includes the hashtag #TheOneYouSeeComing, which is a line from the 2014-2015 run of Moon Knight. Also, Solid Snake is a stealth action hero, so you don't see him coming.

　　Falcon and the Winter Soldier's Sebastian Stan mentioned Isaac and Moon Knight in the same sentence during a virtual press event for that show, Variety notes.

　　In other words, Isaac's attachment to the character was one of the worst-kept secrets in all of Hollywood, but this is indeed the first official post from Marvel Studios confirming it. While Moon Knight is still a ways off, you can see Isaac later this year when Warner Bros.' first Dune film hits HBO Max and theaters on October 1, 2021.
