A great deal of uncertainty swirls around the MCU and its headlining Avengers movies after Marvel Studios dropped its supervillain actor, Jonathan Majors. While Marvel is scrambling to right the ship, new information shared by an insider suggests that Avengers: Secret Wars may have a runtime that will rival Zack Snyder's Justice League.
According to a report by insider Jeff Sneider, Secret Wars will have a massive, exhausting runtime of five hours - hopefully including bathroom breaks. The movie is so long that Marvel is considering splitting it into two parts (groan). This supports earlier rumors that the upcoming movie will be "a giant five-hour movie with a year-long intermission."
The rumor hints that Avengers: Secret Wars, which is scheduled for May 7, 2027, will be followed by Secret Wars Part 2 in 2028. The pair of films will be preceded by Avengers 5 which currently doesn't have a title after the departure of Jonathan Majors.
We have to take this information with a huge pinch of salt as Marvel Studios hasn't officially commented on it. However, it would be entirely plausible given that the source material pits the Avengers, X-Men, and Fantastic Four against supervillains including Kang the Conqueror, Doctor Doom, Enchantress, and even Galactus.
