Superhero movies that never been but could have were...

Wesley Snipes's Black Panther. Definitely would have been dope, and would have brought some real cool and authentic fight scenes with his martial arts. I think the fight scenes, minus the waterfall fights, were the most disappointing parts for me, especially considering how good the fight scenes with the BP were in Civil War.

I'd have most wanted to have seen Spider-Man 4.

Who was planned to be the villain in the original Batman 3?

Patty Jenkins' Thor 2.

James Gunn's Guardians of the Galaxy vol 3

or

Edgar Wright's Ant Man

Tough choice between Burton’s Batman 3 and Raimi’s Spider-Man 4.

I guess judging by what we got instead, I’d choose Raimi’s Spider-Man 4.

The Amazing Spider-Man is okay, but I feel like I could live without it. I’m not sure I want to be in a world where Batman Forever and Batman & Robin don’t exist. Regardless of their quality, they have a fun rewatchability.

A Donner Superman III and a Raimi Spider-Man IV (with Mysterio!) would probably top the list for me. As for the former, I understand somewhat why writers, directors, and producers keep going back to Lex Luthor and Gen. Zod as villains, but I’m amazed that still no one has ever used Brainiac, in many ways a combination of both of them. Years ago I read this comic book called Justice League: Earth 2, which has so many great ideas but executes them poorly, and the Brainiac in that was as creepy as anything, plotting behind the scenes to destroy both worlds. A character like that—utterly inhuman and heartless—would be an interesting change from the lot of somewhat-sympathetic villains nowadays. Almost an anti-Thanos.

And obviously Raimi Spidey sequels. The first one was probably the superhero movie my cousin and I watched the most often when we were younger.

Of course I’d be interested to see what Burton could have done with a third Batman, though that title is awful. (Any more awful than Batman Forever? I don’t know.) But, even if he had directed it and given us a Billy Dee Williams Two-Face, my feeling is still that producers would have forced him to include Robin, another appearance from Michelle Pfeiffer (whom I like, but whose mystique as Catwoman probably would have been lessened by another movie), and another villain other than Two-Face—as well as to have toned it down and made it childish. With that said, anything would have been better than Batman Forever.

I seriously would have loved to have seen a sequel to Superman Returns, but that wasn’t in the cards.

I haven’t seen GotG or Ant-Man, so I can’t comment on those, but I actually like IM3 and, as much as I like IM and IM2, am happy they went with a different tone and director for those. Favreau’s certainly able (and IM is still my favorite MCU flick), but he’s also got absolutely no [directorial] personality. Whereas whoever did IM3 is different from any other Marvel director (closest probably to whoever did Thor: Ragnarok).

One I would have been fascinated in seeing, if only for its monumental bizarreness, would have been that Tim Burton/Nicolas Cage Superman movie. Not as a Superman fan, but just as a fan of incredibly weird cinema.

George Miller’s Justice League: Mortal.
