We're now five movies into the third phase of the Marvel Cinematic Universe - a franchise that started way back in 2008 and which is showing no signs of stopping any time soon. Phase Four will come to a close in 2019 with the fourth Avengers movie (which, up to now, doesn't have a name). Following all of that, all we know about Phase Four is that it will include a sequel to 2017's Spider-Man: Homecoming and a third Guardians of the Galaxy movie - but what other movies could be included in that fourth chapter of the epic franchise? This video will take a look at some ideas about that very subject, based on things that have been seen in the MCU so far (and things that we know are coming in the five remaining Phase Three movies). We'll look at the idea of a Secret Invasion movie involving Skrulls, a Siege movie in which the newly built Earth-based Asgard will be invaded by Norman Osborn and his forces, a movie based on the origin story of Nova AKA Richard Rider, a movie based on the Annihilation story arc, a movie based on the World War Hulk story arc, an all-female Lady Liberators team-up movie, a movie based on the Kree-Skull War story arc, a movie based on the Infinity War and Infinity Crusade story arcs, a movie based on the Thanos Imperative story arc and countless potential movies based on the Marvel characters whose movie rights are currently owned by Fox (mutants, Deadpool, the Fantastic Four, the Silver Surfer, Doctor Doom, Galactus etc). A live action Avengers Vs. X-Men movie, anyone?! We hope you enjoy the video!
