MCU: 8 Billion Dollar Marvel Movies To Justify Buying Fox
3. Marvel Zombies
It's still one of the most unlikely popular arcs in Marvel's library to be adapted, but if Marvel do decide to change the format of the MCU to include more "one-shot" style stories and stand-alones (as DC were planning to do), this would be the perfect opportunity to do a What Ifs style movie for Marvel Zombies.
Why not use every character at their disposal to have a huge zombie apocalypse movie event? It's the kind of one-off opportunity that markets itself - particularly to existing Marvel comics fans - and releasing it around Halloween, while making doubly certain to tell everyone it's NOT an MCU movie would be very clever indeed.
Given how many properties Marvel now have, trying to smush them all together into one coherent narrative is going to be impossible, so having side-lines and alternate time-lines is the perfect answer. And if that means we could one day get Marvel Zombies, even better.
