Are you saying you hat the WHOLW 1st movie of fantastic four is a flashback to the 60’s??!! That would be weird!! I could see fantastic four stuck in the negative zone where they somehow got sent to from the 60’s I could deal with that lol specially if we see them with a surprise cameo in antman3!!
I have absolutely no idea what’s actually happening or what’s being planned, but some rumors have been persistent and there’s some reason and history behind it all.
Way back 20 years ago, before Tim Story, Peyton Reed was attached to Fantastic Four with Fox and he had a FF story set in the ‘60s.
PR obviously didn’t get the job (reportedly because his vision would have been too expensive).
But ever since then, discussion and rumors of a 1960’s FF persisted.
And more recently, there have been rumors not only of a retro FF, but a connection to the Quantum Realm (which fits Peyton Reed’s use of the Quantum Realm as a cross-time realm along with his previous FF work and our knowledge that Kang (a time traveller) will be featured in Ant Man 3.)
We have also recently heard rumors that Rama Tut (a Kang variation) will be the villain of FF.
Piece by piece, it’s just rumor here and speculation there, but if you step back and look at the gestalt, it’s not crazy to think that the FF could be involved in some time shift and they could be involved in some way in Peyton Reed’s Ant-Man 3.
Personally, I think all this dimension travel and time-travel creates a mess and reduces the stakes (“Oh well, that Earth got blown up, but it’s not OUR Earth.”), and I think Marvel should strive to get things back to being more grounded and based on things and settings viewers can feel connected to.
But what I want doesn’t really change what we’re seeing, and what we’re seeing is the FF will be born into an MCU that is a mess and Kang is a major part of it.
