12. Recreate memorable moments or turn them into a character from your favorite movie.
Are you using Marvel and DC characters in the same universe? The concept of these characters is not bad at all. It wasn't a fight scene. It can be as simple and cute as Superman and Batman go for a picnic on the beach. Pack them a small lunch and send them on the road!
Or you can create the whole scene - are they having an intense fight in Kitchenville or the giant beast that is unifying both the Marvel and DC universes for fear of their heads being cut off? Add extra effects like fog or activity in your editing software after shooting for extra magic. You can even add fiery explosions or intergalactic spaceships for even more fun.
