Luke Hemsworth is kinda bland. He wasnt even that good on Westworld. They can do better.
He was in Thor Ragnarok also, so, he's kinda been done.
I don't think it has to be a secondary mutation, but it could be a side effect of using electromagnetic forces. Maybe something to do with the iron in his body and how it affects his blood cells, which then slows down the ageing.
There's lots of cool science fiction that could be used. My only point in that comparison is that offering a sci fi solution that changes is a poor base to point at others who use grounded natural solutions as 'overcomplicating' things. We all know Beginning a career at 85 with mutant powers you've had for 70 years doesn't make sense. We all know having big explosive fights that no one knows about doesn't make sense. Everyone does, that's not overthinking. But, if simple is the goal, if occam's razor is superior, then how simple is your solution?
It doesn't matter if it's simpler. It's the character. Keep it or don't use the character. This whole idea of stripping Magneto of his holocaust origin just makes no sense. This isn't some vague war backstory that could be re-issued for any era. It's the holocaust. The age explanation is simple. Someone posted an idea about it having something to do with the magnetism aspect of his powers. My personal idea is making Magneto one of the many people experimented on with various versions of the super-soldier serum, like Bucky, except it was a failure and only altered his body chemistry to slow his aging rate. It adds a layer to the universe and you could even have a flashback of Captain America rescuing a child Magneto.The audience isn't stupid. It'd be easy to understand for them that Magneto has altered body chemistry or his magnetism powers make him age slower than any other normal mutant.
The audience isn't stupid, you're right. That's why they know when something contrived is shoehorned in, and become less invested in things that happen for dumb reasons, precisely because they do understand. Making Magneto a failed super soldier is pretty high up there in terms of poor changes, I think. We certainly would have crucified Fox for doing something like that, because that's not the character of Magneto. He's not a man out of time. Adding that layer to the universe doesn't make him more interesting, it dilutes the character.
Adaptation is difficult for just this reason. Because Magneto doesn't begin his career as an elderly man, and he is a survivor of WWII, he simply doesn't work as is in 2020 in live action. So you have to lose something for him to make sense like he did in the 60s. Do you lose Magneto's perspective, turning him into a man out of time, or do you lose the particular location where experienced genoicide as a child?
Xavier's powers make it an easy secret to keep.
This is a great example of how simpler is better. When you try to explain simple things like 'we've never heard of the X-Men' with sci fi like "Xavier wiped all the minds" instead of the simple "they're just starting out" you end up with a problem where Xavier has the ability to alter minds at great distances, perfectly. This means that for the X-Men to have any problems or real missions, Xavier either has to be out of commission, or simply forget his powers.
Simpler is better. Another example:
Just say all mutants age slower and live longer, which adds onto the hate of mutants from humans.
Done. No need to over complicate it.
How would humans even know about this? Why would they care? Are there centenarians you hate for living so long?
The simplest answer is that they age normally. Weird aging cannot be simpler than normal aging.
Xavier's School/X-Men
Charles Xavier (Doesn't have to be white, but SHOULD be American)
Instructors (I like the Evolution approach):
Storm, Beast, Logan, maybe Forge...
Students:
Scott, Jean, Jubilee, Iceman, Nightcrawler
Nice. Mine breaks down similar for an initial film:
Mature Adults: Xavier, Moira, Betsy Braddock (pre-Asian), Sean Cassidy, Senator Kelly, Henry P. Gyrich, Fred Duncan, Val Cooper
Young Adults: Scott, Jean, Hank (brown), Candy Southern (open ethnicity), Tessa (Hispanic), Warren W3
Older Teens: Storm, Colossus, Bobby
Young Teens: Nightcrawler, Shadowcat
It sounds like a lot, but it's just Avengers in balancing time and personal storylines. Xavier is Fury, Tessa is Agent Hill. Storm is Tony, Scott is Cap, Jean is Hulk, Colossus is Widow, Betsy is Coulson, Warren is Hawkeye, Hank is Thor, Moira is Eric Selvig, Candy is Pepper, Sean is Sitwell, Fred and Val are the World Security Council. Senator Kelly and Henry Gyrich are Thanos and the Other. Friends of Humanity are the Chitauri, Bobby is actually Henry Dean Stanton's security guard in terms of being one deep conversation and Shadow King is Loki. The particular relationships change, but in terms of screen time and development and audience investment in the characters, that's it. It also means that the main team is just Cyclops, Marvel Girl, Beast, Colossus, Storm and Angel. You could trade Angel for Bobby if you wanted. Then in the sequel, it's three years later, all the older teens are YA, the young teens are older teens and you've got new young and older teens coming through.
Going with that theme, if X-Men: Homecoming 2 is analagous to Avengers: AOU, then Kitty is Rhodey, Kwannon Betsy is Sam, Rogue is Scarlet Witch, Nightcrawler is Quicksilver, Logan is Vision, Exodus is Ultron, Fabian Cortez is Dr. Cho, the Acolytes are the Ultron army, and Candy and her friends are Mrs. Hawkeye and the kids. Asteroid M is Sokovia.
And still going, if XM:HC3 is Civil War, then Sunfire is Black PAnther, Jubilee is Peter, Gambit is Bucky, Alex and Lorna are Sharon, Prez Kelly is T-Bolt Ross, Val Cooper is Ev Ross, Dazzler is Ant-Man, Omega Red is Crossbones, Xavier is FRIDAY, Rose and Papa Logan are Howard and Maria Stark, Phoenix is Zemo... or maybe it's Onslaught or Cassandra Nova. Though of course, some roles switch around so Storm is more the Vision, Scott more then Cap and Logan more the Iron Man.
Also... I found my ideal new Logan.
Short (5'5")
Young (early 30s)
Can fight like a maniac
Tons of geek cred
Not tied to anything else big right now
Affordable price tag
Already been used in another big Disney project, but was wasted
Will instantly generate attention, eyeballs and goodwill for the project
Iko Uwais (The Raid: Redemption)
I think I said before Wolverine is pretty fundamentally White because of his class, time period and location, but when you get a fit this close, you see if you can bend a little bit, and convenient enough, Logan is an illegitimate child of the groundskeeper, who could be any race. Plus, if Papa Logan were East Asian, that would actually explain Wolverine randomly hopping off to Japan years later. That means it makes Wolverine's story more grounded, on top of all the other plusses. My only question: can he grow facial hair?
