Okay, so hear me out.
We have had two mediocre attempts at bringing The Fantastic Four to the big screen. Two attempts that included an origin for them. Now in this new MCU version of the characters I am on the fence on whether or not to include an origin. However, IF you do I think they should do what they are doing with Captain Marvel and have it set in the PAST of the MCU and perhaps tie Captain Marvel and the Fantastic Four together as a sort of cause and effect.
As we know the Skrulls are going to be the main villain in Captain Marvel and after that film ends let's say younger Nick Fury has an idea to get the Richards and the Storms and Grimm together to figure out some of the technology of the Skrulls and whatnot and that is what sends them into space and hence puts them on the road to getting their powers either on a related or unrelated circumstance. I think creating the Fantastic Four out of the aftermath of Captain Marvel and either making them sleeper Agents of Shield or perhaps in their film after fighting Doom or maybe meeting the Silver Surfer and Galactus on another planet they somehow get marooned and have to make their way back to earth could be awesome, it keeps the team before all the rest of the heroes timewise, and instantly builds up their cred and respect in the same way Captain America and I am assuming Captain Marvel's will be.
If not who has any better ideas? Let's discuss. :-)
