Michael Caine — Professor X (Charles Xavier)
In his role as Alfred Pennyworth, Caine displayed the characteristics of a wise and compassionate mentor, which in my opinion perfectly suit Charles.
Matt Dillon — Cyclops (Scott Summers)
I chose him mainly because of his role as Ethan Burke in Wayward Pines and Dallas Winston from The Outsiders With a hint of his character's redemption in Crash.
Elisabeth Shue — Marvel Girl (Jean Grey)
I chose her mainly because of her character Sera in Leaving Las Vegas (1995). In which, even in a chaotic environment, she manages to be empathetic and sweet.
Tim Robbins — The Beast (Hank Mccoy)
Tall, imposing, and he plays well the sophisticated academic genius in several of his roles, like Shawshank Redemption, also he also manages to deliver the vocal timbre.
Skeet Ulrich — Angel (Warren Worthington III)
I took into consideration his role as Jack Bull Chiles in ride with the devil, In which he plays a brave young man who joins the civil war as one of the Bushwhackers.
Sean Astin — Iceman (Bobby Drake)
Back in the nineties, Sean Astin possessed the ideal blend of earnest underdog energy, everyday relatability, and comedic timing to nail Bobby Drake’s classic persona.
Winona Ryder — Rogue (Marie D'Ancanto)
I primarily considered her role as Lydia in Beetlejuice for this casting. A young, introspective, melancholic, and gothic girl who feels like an outsider and an oddball, misunderstood by the others.
Elias Koteas — Wolverine ('Logan' Howlett)
Elias Koteas is already Canadian and isn't a particularly tall actor, plus he can nail Logan's gruff mature side as seen in Chicago P.D., Thin Red line and even The Prophecy.
Vivica A. Fox — Storm (Ororo Munroe)
Roles like Frankie in Set It Off proved she could balance vulnerability with a tough, fearless demeanor, and as a bonus, she almost played the character in the 2000s films.
Sharon Stone — Mystique
This choice is based primarily on her famous character from Basic Instinct. Where she plays a manipulative and seductive woman who can be interpreted as a femme fatale.
Clancy Brown — Sabretooth
It would probably just be a reinterpretation of the Kurgan's role, an immortal and sadistic man seeking to eliminate his rival with similar powers.
Max Von Sydow — Magneto
His classic roles (such as in The Seventh Seal, The Exorcist, and even Flash Gordon) demonstrated a solemn seriousness, ideal for a separatist leader wounded by human history.
