If i had it my way... Marvel would put out 3 films a year 2 big films and one smaller film (2 summer, one winter)
Phase II will obviously consist of sequels
-Iron Man 3
-Captain America 2
-Thor 2
-Incredible Hulk 2 (hopefully)
-(eventually avengers 2)
-and possible Black Widow/SHIELD film
this is why is suggest 3 films a year.. its kind of a must if we want any new characters announced. They obviously want to build up there universe, so i believe it's important to pick characters that DO expand the marvel universe. For me... it's location location location...
-Black Panther: He's pretty much a must imo, he's an avenger (great for avengers 2), he's a leader of a nation, Wakanda could be so inspiring and beautiful.. a futuristic/modern wealthy african nation (that alone could actually inspire many people) His film would also offer many amazing visuals we've yet to see in movies.
-Namor: he's an integral character to the Marvel Universe... and he brings us Atlantis. It would be a highly ambitious film.. having most scenes underwater. Not the most likeable character, so he will be tricky to work with. you gotta make him tough, make him an ass.. but in a way make him vulnerable and sensitive so the audience can see why he's such an ass. He could even have a captain america cameo with an invaders scene... there's really alot you could do with him.
-The Savage Land (Ka-zar, Zabu, Shanna, Devil Dinosaur, Sauron (if fox doesnt own him). Don't make the film about a hero, but the island itself (yes the main characters of course would be Ka-zar and Shanna, but you get what i mean). We've yet to have a modern day movie where a Tarzan like character.. enter a "Turok" type world full of dinosaurs and alien technology. I think it'd be huge.. and even bigger if released before JP4 (if that ever sees the light of day) I really think marvel should beat them to the punch
last but not least...
-Cosmic Marvel.. cosmic marvel is tricky.. because so many space characters (silver surfer, galactus, super skrull, annihilus, and probably blastaar and the Shiar too) are all owned by fox, so they'd really have to work around that. Best choices would obviously be Captain Marvel, The Inhumans, and Guardians of the Galaxy.
these would be my major players for a Phase II
as for littler films that are far more self contained rather than expansive would obviously be
-Dr. Strange
-Antman
-Heroes for Hire (screw individual luke cage/ironfist movies.. just go ahead and combine them)
and last but not least...
-The Runaways (totally do it in the spirit of Super 8 and the Goonies in showing the Marvel universe from the eyes of children/teens)
