With "Secret Wars" aiming to be an "Endgame"-level event film, there will undoubtedly be some fans who will want to prepare by watching the entire MCU canon — at least, until they realize the time commitment required to do so. As of the release of "Secret Invasion," it would take approximately 117 hours to watch every single movie, TV series, short, and special presentation so far. Our rough (and very conservative) estimate also leads us to believe that there will be at least 50 more hours of content dropping between now and "Secret Wars," which might make even a Multiverse Saga rewatch entirely unattractive to most.
Oddly enough, however, the one good thing about the arguably scattershot nature of Phases Four and Five is that there are already plenty of titles you can skip while pregaming for "Secret Wars." A must-watch list of films includes "Doctor Strange in the Multiverse of Madness," "Ant-Man and the Wasp: Quantumania," and very likely "Deadpool 3" (for its all-but-confirmed multiversal antics), "Fantastic Four," and "Avengers 5." Meanwhile, of all the many Disney+ Marvel series, "Loki" and "What If...?" seem most revelant to "Secret Wars."
If you want to be thorough, you could also revisit more isolated projects that feature prominent characters in the future MCU, including "The Falcon and the Winter Soldier," "Black Widow," "Shang-Chi and the Legend of the Ten Rings," "Hawkeye," "Ms. Marvel," "Black Panther: Wakanda Forever," "The Marvels," "Captain America: Brave New World," "Thunderbolts," and "Ironheart." Together, these 16 films and series will likely add up to about 50 hours — the length of the Infinity Saga rewatch many fans did before "Endgame."
