Basically, if this movie was real, it would make all of the money.
There's enough movies, TV shows, and video games starring all the major Marvel and DC superheroes that it's now possible for someone to make this awesome trailer for an imaginary movie in which all the Marvel characters fight all the DC characters.
Since the film rights to these characters are split among several rival film studios, it's unlikely an actual "Marvel Vs. DC" movie could ever exist, so we're going to have to settle for getting our nerdy thrills from MR866 and Alex Luthor's top quality movie mashup.
