You mainly need to catch up on the key movies and shows that introduce the Thunderbolts team members and their boss‑type figures in the MCU.

What do I need to watch before Thunderbolts?

If you don’t want to rewatch the whole MCU, focus on the projects that set up Yelena, Bucky, Red Guardian, Ghost, U.S. Agent, and Valentina, plus the post‑Endgame world.

Absolute essentials (short list)

If you only have time for a handful, these are the most commonly recommended “musts” before Thunderbolts.

  1. Black Widow (2021) – Introduces Yelena Belova, Red Guardian and their family history; widely called the single most important lead‑in to Thunderbolts.
  1. The Falcon and the Winter Soldier (Disney+) – Develops Bucky post‑Endgame and introduces John Walker/U.S. Agent and Valentina.
  1. Hawkeye (Disney+) – Continues Yelena’s story and her grief/anger after Natasha’s death.
  1. Avengers: Infinity War and Avengers: Endgame – Give you the broader context of the current MCU status quo and the emotional weight around Natasha’s sacrifice that hangs over Yelena and others.

These four “pillars” (plus the two Avengers movies) will make most character motivations in Thunderbolts feel clear and emotionally grounded.

Strongly recommended extras

If you want a more complete Thunderbolts prep, these titles deepen specific characters’ backstories.

  • Ant‑Man and the Wasp (2018) – Introduces Ghost (Ava Starr) and her powers; helpful so she doesn’t feel like a total stranger.
  • Black Panther (2018) and Black Panther: Wakanda Forever (2022) – Flesh out the Wakanda side of the MCU, which several lists include as useful context for geopolitics and certain supporting players.
  • Captain America: The Winter Soldier (2014) – Key for understanding Bucky’s trauma and Hydra past.
  • Captain America: Civil War (2016) – Shows the events that lead to the Black Widow timeframe and further evolve Bucky’s story.

Some guides also flag Captain America: Brave New World as a relevant lead‑in because it continues the political threads and Bucky’s path in the modern MCU.

“Deep cut” but optional

If you’re a completionist, these help but aren’t necessary to follow the plot.

  • Other Phase 3/4 ensemble titles (like more Avengers appearances) to get general MCU familiarity.
  • Disney+ series that sit around the same era (e.g., Loki , WandaVision) – nice for multiverse context but not directly Thunderbolts‑focused.

Most commentators emphasize that Thunderbolts is being written so you can follow it even if you’ve skipped some of this, but the more of the “core” list you’ve seen, the more payoffs and character beats will land.
