Let's face it. There is not a single Marvel fan who hates the Marvel Cinematic Universe. For the first time we are able to get practically all the Marvel characters into one single universe. So the obvious question is: which of the heroes will get their own film and join Earth-199999's Avengers? Here is my personal list (no specific order).
With Rhomann Dey and Richard Rider confirmed for Guardians of the Galaxy, you can't help but ask if there will ever be a film for the intergalactic police force. Sure, such an intergalactic police force film gives us memories of 2011's Green Lantern, but there is always a possibility, especially with Sam Alexander.
This might be a bit of an out-there possibility, considering his ownership by Fox and somewhat New Line Cinema, but you have to consider just who Deadpool is. Not only is his origin all convoluted, allowing for some change from X-Men Origins, but he is a stand-alone character with his own ego. Now if he can only be family-friendly enough to get past Disney...
3. Daredevil, Punisher, Blade, and Ghost Rider
You might think these are also out-there, but these characters were taken back by Marvel Studios. Daredevil's status on getting a movie is unknown, Punisher's is being tossed around, Blade is getting worked on, and Ghost Rider is in the bucket for now.
4. Spider-Man, X-Men, and Fantastic Four
This is the clearest out-there, but I have actually thought of a situation that I can't believe no one else thought about. How about doing a multiverse crossover between Earth-120703, Earth-199999, and Earth-10005? There may be a couple of corporate issues, but it would be so awesome!
I have no real descriptions for the following, but here are some suggested properties I would like to see: Doctor Strange, Black Panther, Iron Fist, Luke Cage, Vision, Dazzler, Inhumans, Nighthawk, Falcon, War Machine, Hawkeye, Black Widow (I know those last four appeared in other films, but who cares?) and Ms. Marvel. Got any more?
