We're just three months away from Avengers: Endgame, the sequel to Infinity War and the culmination of the entire Marvel Cinematic Universe until this point. And honestly, well played Marvel, because we have no idea what to expect from Endgame. The heroes snuffed out by Thanos' snap will probably be back in some form, and we have to imagine the quantum realm will come into play, but beyond that it's really anyone's guess. Of course, we have our theories, but the best way to prepare for the end is to watch all that came before. Any excuse for an MCU marathon is a good one, but this time it feels especially vital.

To prepare, here's a handy guide for where to watch every movie in the Marvel Cinematic Universe online before Endgame hits theaters on April 26.
