What movies should I watch before Avengers: Doomsday?

If you want the most useful prep watch list for Avengers: Doomsday, focus on MCU stories that establish the multiverse, branching timelines, and major returning characters.

Best core watches

1. Loki (Seasons 1–2)

   • Best foundation for the TVA, branching timelines, and multiverse rules.

2. Doctor Strange in the Multiverse of Madness

   • Useful for understanding multiverse consequences and the broader idea of incursions.

3. Deadpool & Wolverine

   • Helpful for the Void, variant logic, and multiverse-crossing chaos.

4. Avengers: Infinity War and Avengers: Endgame

   • Good for the broader Avengers context and the emotional legacy of the MCU up to this point.

5. Iron Man

   • Worth revisiting for Tony Stark’s core character arc and MCU history.

If you want extra context

• Spider-Man: No Way Home — strong multiverse crossover context.
• What If...? — more variant and alternate-timeline ideas.
• Fantastic Four-related material — optional background if you want more context on that team, though the exact connections to Doomsday may still change.

Short version

If you only have time for a few, watch:
Loki → Multiverse of Madness → Deadpool & Wolverine → Infinity War → Endgame.

Caveat

Some Avengers: Doomsday details may still change before release, so it’s worth checking the latest official Marvel info closer to the movie date.
