Reasons Why It Won’t Happen:
1. His schedule is to busy
Johnson is a very busy actor who makes multiple big-budget films along with TV shows and specials every year. Even with the film still at least three years out, it’s hard to predict Johnson’s availability. Delays in production happen all the time, and the Studio may feel with too much riding on this “big debut,” it may not be worth the risk.
2. He’s already doing Black Adam
From a contract standpoint, he may not be allowed to do it. Johnson is already attached to another Superhero project called Black Adam. The DC anti-hero is set to begin filming later this year, with a release date slated for December 2021. It doesn’t happen often, but sometimes clauses are put into contracts to prevent actors from playing similar roles with rival studios that would conflict with their release. It’s not known, but Warner Media, who’s backing the film, could have done just that. Also, Marvel Studios could feel that marketing Johnson as another Superhero could be too conflicting. With his current global appeal however, that seems unlikely.
3. He may be too old
The final reason, and perhaps most logical, is that he may be too old. At 47, Johnson’s appearance still allows him to play roles set in their 30s. However, if Marvel Studios decides to take a similar route as Fox did in the 2015 version, it could set all the characters in their early 20s. It’s not known or even reported on how the fan-favorite team will be portrayed, but it is a possibility. If true, it would instantly rule him out. Sadly enough, this would also rule fan’s dreams of John Krasinski and Emily Blunt as Reed Richards and Sue Storm.
Who knows what will happen with how the film shapes out. Outside of Marvel Studios head Kevin Feige’s comments at Comic-Con in 2019 that a Fantastic Four movie is “happening,” there has been no new information on it. Fans, like myself, are left to wander how the team will make it’s MCU debut. Even though my selection may seem farfetched or insane to some people, it sure is fun to dream.
