Seriously, I hope this footage shows up online soon, because my description is not going to do it justice. There was a lot going on here. We see a closeup of an eye, and Professor X (Patrick Stewart) asks, "What's the last thing you remember?" "I had a glimpse into the past," someone responds. Professor X tells Wolverine, "You're going to have to do for me what I once did for you."
And this is a dark dystopian future, where the dark, fetishy costumes are looking more dirty and distress and messed up, and Professor X and Magneto seem weary and filled with dread.
We see flashes of all our favorite mutants, including Storm against a stormy sky, Ellen Page as Kitty Pryde, Omar Sy as Bishop, and some others that I couldn't immediately identify. Plus Ian McKellen as Magneto.
We learn that Professor X and Magneto have come together "side by side, to end this war before it ever begins."
Wolverine asks, "So I wake up in my younger body, and then what?" Professor X responds, "Find me, convince me of all this." And Magneto chimes in that Wolverine will find younger Magneto a different person, "a darker person." We catch glimpses of 1970s versions of Magneto and Professor X — with a lot more hair and a lot more fire to them. Professor X has a crazy beard and a 1970s groovy outfit, while Magneto is a rabble rousing leader who levitates. And we see Young Mystique crying, while Young Beast is howling.
Back then, Professor X says, "I was a very different man. Lead me, guide me, be patient with me."
Wolverine responds, "Patience isn't my strong suit."
We catch glimpses of other stuff — Young Magneto using his powers to pull a distressed Mystique along the floor. Young Magneto descending from the air looking scary. There is a mysterious opening under the Oval Office, revealed by the oval opening up like a trapdoor. And Richard Nixon looking weird and terrifying — and then a shapeshifter walking down the street changing his appearance. There is a LOT of stuff blowing up, and Young Professor X using Magneto, and the Beast attacking, a woman walking away from an airplane, and a military setting.
Young Professor X says, "I don't want your suffering. I don't want your future."
And then Old Professor X is face to face with his younger self. He says: "Please. We need you to hope again." It's an actual spine-tingling moment. Actual goosebumps here.
