It's safe to say that we will never see the Marvel and DC cinematic universes collide on the big screen. But thanks to YouTuber Mr88668866, we have an idea of what that epicness could look like in his fan-made Avengers Vs. Justice League trailer. He uses a ton of footage from several different comic book films and does a great job editing them all together. This turned out really entertaining, so I hope you enjoy it!
