Well, the way I’d imagine things; starting at 2020:
Planet Hulk (Annihilation 0)
Spider-Man and the New Avengers
Guardians 3 (Annihilation 1)
Hulk: Future Imperfect (Kang 0)
Captain Marvel 2 (Annihilation 2)
New Avengers: Kang Dynasty Part 1
Inhumans 2 (Annihilation 3)
New Avengers: Kang Dynasty Part 2
Nova (Annihilation 4)
I figure the most you can ask out of any actor is a ten year commitment. With RDJ et al throwing up their hat in 2018.
I figure Ruffalo sticks around til 2022, but if not a recast isn’t a bad move.
The good thing about the Hulk movies is it gets him out of Earth which is a shit setting for him and you can put Annihilation Wave easter eggs in Planet Hulk, and then maybe Kang Easter Eggs in Future Imperfect - teasing out both of the big events.
Runaways should be a big fun franchise if handled right. Teenagers hopping through dimensions fighting Lovecraftian god-demons is a fun concept, and you can throw in a Dr Strange cameo or what-have you, and keep the kids as children of villains - maybe make Molly an Inhuman - switch them around a bit.Mostly this is mystical, though, Nico stays but maybe Chase isn’t so technical, and maybe Old Lace is a little revised. For some fun you could probably visit Asgard in one of the films.
Spider-Man becomes your new centrepiece after Iron Man bows out, and thus he should be fore-front of an Avengers franchise which introduces some new young characters. I’d imagine Kamala Khan, maybe Nova, probably take advantage of some of the old guard lying about like Ant-Man, Wasp, Black Panther but they’re bit-players. Wonder Man might fit in here. Maybe throw in Winter Soldier as a version of Cap. - but the theme here is the young heroes aware of a threat the old guys are too stupid to recognise.
I think you build a Kang story around Iron Lad, and use him to take the younger, funner Avengers on a time-travel story. Something that probably wouldn’t work with the earnest originals. You could have a little history of the Marvel U for the die-hard fans (bearing in mind the universe will be 15 years old at this point and seen roughly three generations of kid movie goers become teenagers or adults).
I think the Annihilation story is basically just your big Space Opera, with a cast of characters. I prefer keeping the Inhumans in this genre but I don’t think that’s what Marvel have planned. I think you have to scrap Annihilus as the villain, - and considering the Dire Wraiths and the Phlanx are probably out, you have to pick something else - but the exact nature of the threat isn’t really what matters here.
I think Jim’s right and that Nova could be a big fun franchise, but I’d prefer to focus on Spider-Man, the Runaways and the younger Avengers for the time being - it seems to me that ensemble pieces sell, and I’d say they both have good opportunities to connect with new audiences. Having him intro in 2023, 2024 leaves plenty of room for future tentpoles.
I think Power Pack is probably best served as a Big Hero 6 style animation and, while I love Adam Warlock, I don’t envisage him as relatable enough to build a film around.
Basically, I think you need to take the current new blood (Spider-Man, Guardians, Captain Marvel) and use that as a spring-board to attract audiences to even younger blood - and that’s where you build your franchises.
