Now, Holland is about to get his first solo outing as the web-slinger in Spider-Man: Homecoming, while Affleck also has a Batman movie in the works.
It imagines a movie where multiple Batman and Spider-Man movie universes collide, bringing together three Spideys and as many Batmen for a single massive battle.
Spider-Man and Batman may never face off on the big screen, but a new fan-made trailer shows how it might happen if they did.
The trailer begins with Spider-Man and Batman facing off, before the voiceovers explains the multiverse concept and Ben Affleck flicks the switch on a machine that brings them all together.
