...sounds crazy! A teaser was leaked at Comic-Con, here's a summary...
We see a closeup of Patrick Stewart's eye, and someone (Stewart) asks, "What's the last thing you remember?" Professor X (Stewart) responds, "I had a glimpse into the past."Then Professor X tells Wolverine, "You're going to have to do for me what I once did for you." We slowly zoom out from Professor X's aged face, and then we see him with a Cerebro helmet on, and later coming out of the Cerebro chamber.
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 Ian McKellen's Magneto seem weary and filled with dread. They're in a war chamber in front of a table that shows how badly things are going. Wolverine even has a bit of gray in his facial hair.
We see flashes of all our favorite mutants, including Storm against a stormy sky, Ellen Page as Kitty Pryde, and some others. And there are futuristic-looking mutants, including Omar Sy as Bishop, and some others I couldn't identify wearing dramatic Mad Max-y makeup.
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. Young Professor X has a crazy beard and a 1970s groovy outfit with an X-shaped light on his face, while Young Magneto (Michael Fassbender) is waving a gun.
We see Young Professor X blowing dust off a white globe.
Back then, Professor X says, "I was a very different man. Lead me, guide me, be patient with me." We see Young Professor X putting his hands on someone's face as he tries to understand. Maybe Wolverine's face?
Older Wolverine responds, "Patience isn't my strong suit."
And then blue glowing hands are gripping Wolverine's head, sending him back in time into the body of his younger self.
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 protests in the street, and Bolivar Trask (Peter Dinklage) addressing a government hearing. And Richard Nixon looking weird and terrifying — and then Mystique walking down the street changing into a man in a pimp suit.
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. We glimpse Professor X shielding his face from an intense white light, and the Cerebro machine exploding.
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.
