    Here Are 45 MCU Details To Remember Before "Avengers: Endgame"

    "We're in the endgame now."

    With 22 movies spanning 11 years, the Marvel Cinematic Universe is about to close a monumental chapter when Avengers: Endgame hits theaters.

    And with such a huge milestone approaching, I took it upon myself to rewatch every single MCU movie in preparation.

    So, below are some of the important moments that led us to Avengers: Endgame:

    1. Let's start where it all began: In Iron Man (2008), S.H.I.E.L.D. is first mentioned when Coulson attempts to debrief Tony on his captivity in Afghanistan.

    2. Also, in the Iron Man post-credits scene, Nick Fury makes his first apperance ever when he arrives to tell Tony about the "Avengers Initiative."

    3. In The Incredible Hulk (2008), Tony approaches Thaddeus Ross at a bar and tells him that a team is being put together.

    4. In Iron Man 2 (2010), Dr. Wendy Lawson's Project P.E.G.A.S.U.S. from Captain Marvel and Hank Pym's Project G.O.L.I.A.T.H. from Ant-Man and the Wasp are both mentioned by Tony.

    5. Also in Iron Man 2, the new element that Tony creates mimics the power of the Tesseract — you can spot a drawing of the Tesseract in Howard Stark's notes.

    6. In Thor (2011), we get the first glimpse of the actual Tesseract/Space Stone when Nick Fury shows it to Erik Selvig during the post-credits scene.

    7. Also in Thor, you can spot a right-handed Infinity Gauntlet among Odin's treasures — in Thor: Ragnarok, Hela reveals that it's a fake.

    8. In Captain America: The First Avenger (2011), Howard Stark talks about vibranium, a metal that Stark Industries discovered in Africa — of course, he later makes Captain America's shield out of it.

    9. Also in Captain America: The First Avenger, Howard retrieves the Tesseract from the bottom of the ocean after it was lost by Red Skull and Steve.

    10. In The Avengers (2012), we get the first glimpse of the Mind Stone when Loki arrives in NYC and wields the stone in his scepter.
