Well, since they hired Watts again. I assume they’ll take a similar approach they did with Spider-Man and refrain from retelling the origin for a third time, but then again, the FF origin isn’t nearly as iconic as Spider-Man’s so who really knows?
I will point out it’s still possible their origin can still be done in other MCU related movies and shows before their first film. After all, we first saw Black Panther’s origin story in Civil War two years before his solo movie came out. This question really depends on whether or not they really think the origin story is worth retelling again, and if they do it in a fresh way.
Personally I still think Marvel will mostly avoid the origin story in the movie but hint at it dialogue. One idea I’ve tossed around before is that they could handle it in the form of an animated opening sequence co-narrated by the team that would serve as cliff-notes for origin. So imagine the animated Birds Of Prey opening where Harley Quinn is narrating her origin to the viewer(can’t link here due to strong cursing) but it’s with the Fantastic Four doing this.
Or they could do what they did with the Incredible Hulk and just do something like this again.
This is a neat opening that sums up everything you to know about the Green Goliath. So maybe something like that where you see the visuals play out with no dialogue where you see the space travel, you see the transformation sequence, and you see them putting their hands together in order to swear to use their powers to make the world a better place — all covered in little over a minute instead of taking over 2 hours to tell in a movie like in the previous movies.
When I watch that trailer, these iconic comic panels come to mind:
