But it makes no sense to begin with Iron Man; the Fantastic Four is the cornerstone of the Marvel Universe and the movies should have started with the FF. But the FF also shows us that Constantin Film -- the company that produced the 1994 Roger Corman film -- was either not able or interested in launching a blockbuster series of movies. Someone with deeper pockets would have had to buy the license from them.
Let's say Universal, flush from the success of Back to the Future, felt what few movie companies have ever felt -- both confidence in the superhero genre and respect for the original source material. So they bought the license to the Fantastic Four from Constantin, budgeted $20 million for the movie, and green-lighting their movie immediately. A script would be written combining the first two issues of The Fantastic Four, giving them an origin story, keeping it a period story set in 1961, and having them discover the Mole Man and Monster Isle, a place where alien Skrulls have been creating monsters.
Because Universal would need a big special effect budget, they would try to cut costs on casting by staying away from big names. For Mr. Fantastic, they would go to television and cast Robert Urich. Although a critical failure in movies to date, Urich was on fire on television in Spenser.
The casting of The Thing would seem an unusual one, but bear in mind that the actor would be wearing a full-body costume for much of the movie (and animatronics would handle The Thing's face in close-ups), so this actor would have to be able to act mainly through his voice.
This is a bit hypocritical of me -- I have faulted the 2005 Fantastic Four film for over-sexualizing the matronly Invisible Girl -- but I cannot resist the chance to cast Rebecca De Mornay as Sue Storm.
As for the Human Torch...it is no secret that Johnny Storm is not a deep character, and for half of the movie he would be covered by animated flame (traditional cell animation, of course), so it is least important that Johnny be played by a big name actor.
I'm really going to go out on a limb here and cast then-unknown teenager and skateboarder Matthew Lillard as Johnny. Many years later, Matthew would show incredible talent by turning himself into a living cartoon character, as Shaggy in the Scooby Doo movies. And having two connections to Scooby Doo (Frank Welker voiced both Fred and Scooby Doo) in the movie amuses me.
This movie would be about 109 minutes long, average for a top-grossing movie in 1986, and a huge success -- if it was as successful as the Iron Man movie of 2008, it would be the 8th most successful movie of 1986, edging out Eddie Murphy's The Golden Child and earning, oh, let's say $80 million. The four times their investment back would be almost identical to Iron Man's 2008 returns.
Work would begin on a sequel to the hit Fantastic Four movie already, which would come out two years later in 1988 (as fast as Star Trek movies were coming out at the same time). But, to keep momentum going, Universal would already be pushing through a Hulk movie.
Roger Corman's New World Television company already had plans to make a "The Incredible Hulk Returns" TV movie with Bixby-Brandon Productions. Universal had already had faith in The Incredible Hulk in the 1970s, as it was their TV show. Now it would be an easy way to continue the Marvel Cinematic Universe, would buy into this project, give it a $21 million budget, and get it a theatrical release.
Rather than continuing the 1970s' TV show, this would be a reboot taking place in 1962. Like the Fantastic Four movie, this one would follow the original comic books closely -- Bruce Banner would be a scientist working for the U.S. Army, he would be irradiated by a gamma bomb while saving the life of Rick Jones, would hide his transformation into the Hulk from Betty Ross, while being hunted by General "Thunderbolt" Ross. Bruce was betrayed by an assistant working for a Russian known as The Gremlin, but The Gremlin would turn out to be an agent of the Skrulls. The Skrulls would take the place of the Toad Men from Hulk #2. Bruce would be on one of the Skrull ships seen in the Fantastic Four movie and crash the ship after turning into the Hulk on it.
