Movie Franchises That Should Definitely Have Crossover Events

Every few years, Marvel and DC Comics have some kind of crossover one-shot or mini series with each other, and plenty of fans have been hoping the respective cinematic universes would eventually get around to doing the same.

Could we ever see such a massive movie crossover between DC and Marvel? Nothing is impossible, of course, but there is the pretty big question of whether or not either Disney or Warner Bros. would be comfortable trusting their IPs, at least in part, with their competitors on a temporary basis. On the flipside, who wouldn’t pay to see a live-action throw-down between Superman and Thor?
