Unfortunately, while Marvel and DC have done the occasional crossover in the pages of their respective comics, it seems like the longest of shots that we would ever get something like that on the big screen. If a deal between WB and Disney that would allow for such things impossible? Maybe not, but this would be a step above Disney and Sony sharing custody of Spider-Man. This would be a studio deal for the ages. Until then, we’ll just have to experience the, probably unlicensed characters in costumes and fan video to see what a battle like this would really look like.
