5. Avengers/Guardians Of The Galaxy Crossover?

Avengers GOTG

If this doesn’t happen in Avengers: Infinity War, then it’s never going to…

Based on the events of the first movie, you have to imagine that the Guardians of the Galaxy will have some sort of involvement in the fight against Thanos, and despite the title, there’s a very good chance that this is going to be a full on team-up movie. Seeing Captain America fighting alongside Star-Lord, Hulk meeting Drax and Iron Man exchanging quips with Rocket Raccoon (to name just a few possibilities) is extremely appealing, and bringing these two franchises together would be a very smart business decision for Marvel.

Usually, throwing all these characters into a single two hour release would spell disaster, but across an epic two part adventure? Regardless of whether it’s set on Earth or space, this has to – and likely will – become a reality.
