Considering that DC/Marvel crossovers appear to be a thing of the past even in comic books, it seems unlikely we'll see Thor face Superman on the big screen in our lifetimes. Undeterred by any corporate differences, a certain Alex Luthor (no relation, presumably) has assembled an epic trailer that gives us a taste of what such a live-action crossover might look like. And it's pretty glorious.

Using footage from sources ranging from The Avengers and Iron Man to The Flash and the rejected Wonder Woman pilot -- you'll even see Injustice: Gods Among Us -- Luthor crafts a teaser that pits Batman against Iron Man, Hawkeye against Green Arrow, Black Widow against Black Canary, Loki against The Joker ... the list goes on.
