You’ll get the most out of Thunderbolts* if you’re familiar with each team member’s backstory and the shady “recruiter” pulling strings behind the scenes.

Below is a watcher‑friendly guide plus a bit of current fan/forum chatter about “what movies should I watch before Thunderbolts.”

Core must‑watch list (minimal homework)

If you only have time for a few projects, these are the ones nearly every guide highlights as essential prep.

  1. Black Widow (2021)
    • Key for: Yelena Belova, Red Guardian, Taskmaster, the Red Room and their “found family.”
 * Why it matters:
   * Establishes Yelena’s personality, skills, and trauma, which directly fuel her arc in Thunderbolts*.

   * Introduces Alexei (Red Guardian) and Antonia (Taskmaster) and shows how badly the Red Room messed them up, setting up their need for redemption or payback.
  1. The Falcon and the Winter Soldier (Disney+)
    • Key for: Bucky Barnes, John Walker / U.S. Agent, Valentina Allegra de Fontaine (Val).
 * Why it matters:
   * Tracks Bucky’s struggle to make amends and redefine himself after decades as the Winter Soldier.

   * Shows John Walker go from decorated soldier to controversial Captain America replacement to something much darker.

   * Introduces Val’s whole “recruiting unstable but useful people” shtick, which is basically the Thunderbolts* setup.
  1. Ant‑Man and the Wasp (2018)
    • Key for: Ava Starr / Ghost.
 * Why it matters:
   * Explains her phasing powers, her painful origin, and why she’s desperate enough to cross moral lines.

   * Thunderbolts* treats her as a redemption‑in‑progress antihero, which hits harder if you’ve seen how broken she was here.
  1. Hawkeye (Disney+)
    • Key for: Yelena Belova’s grief and her post‑Blip mindset.
 * Why it matters:
   * Shows Yelena in the present day, dealing with Natasha’s death and clashing with Clint.

   * You see how she processes loss, humor, and violence, which carries straight into her Thunderbolts* vibe.
  1. Avengers: Infinity War (2018) and Avengers: Endgame (2019)
    • Key for: Natasha’s sacrifice, the Blip, and the emotional stakes the Thunderbolts are living in.
 * Why they matter:
   * Endgame, especially, is repeatedly flagged as essential because Natasha’s death is a huge emotional pillar for Yelena and others.

   * Infinity War is needed mostly to set up the context for Endgame’s events and the state of the world that follows.

Strongly recommended “character arc” set

These projects flesh out specific Thunderbolts members and the tone of their world.

  1. Captain America: The Winter Soldier (2014)
    • Focus: Bucky’s transformation into the brainwashed assassin and Steve’s attempt to save him.
 * Why watch: Deepens your understanding of Bucky’s guilt and trauma, making his search for redemption in Thunderbolts* more meaningful.
  1. Captain America: Civil War (2016)
    • Focus: Bucky’s past crimes, Avengers infighting, the Sokovia Accords.
 * Why watch: Shows how Bucky was used as a weapon and how that tore the Avengers apart, giving context to why governments would turn to a morally grey team like the Thunderbolts.
  1. Captain America: The First Avenger (2011)
    • Focus: Young Bucky in WWII, his relationship with Steve.
 * Why watch: Not mandatory, but it makes his whole journey from charming soldier to broken assassin to uneasy hero feel epic.

Nice‑to‑have extras and future tie‑ins

Some outlets also flag these as useful, depending on how deep you want to go.

  1. Captain America: Brave New World (if released where you are before Thunderbolts*)
    • Why: Early info suggests Bucky shows up in a political thriller context, possibly feeding into his status by the time of Thunderbolts*.
  1. Any appearances of Valentina Allegra de Fontaine
    • She pops up in post‑credits scenes and cameos to recruit “problem” heroes and antiheroes, further setting up the Thunderbolts concept as a kind of shadow team.
  1. Other MCU ensemble stuff you may have missed
    • Some guides casually mention that if you’re foggy on the Blip, the Avengers, or SHIELD/HYDRA history, revisiting key ensemble movies (like Avengers, Winter Soldier, Civil War, Infinity War, Endgame) keeps all the politics and legacy drama clear.

Fan / forum consensus and debate

Public forum threads about “what do I need to watch to be prepared for Thunderbolts*?” tend to cluster around a few viewpoints.

  • “Bare‑bones homework” crowd
    • Some users say you can walk in mostly fine if you just know who Yelena, Bucky, and Ghost are, and they recommend only Black Widow, Falcon and the Winter Soldier, and Ant‑Man and the Wasp as non‑negotiables.
  • “Character‑completionist” crowd
    • Others argue Thunderbolts* is essentially a mash‑up of multiple redemption arcs, so they push for the full Bucky trilogy (the three Captain America films plus Falcon and the Winter Soldier) and Yelena’s full path (Black Widow + Hawkeye + Endgame context).
  • “MCU‑fatigued but curious” crowd
    • There’s also a group that openly says they’re not hyped for another Marvel team‑up, but they’re still interested because of characters like Sentry, Ghost, and Yelena and want a curated watchlist that doesn’t require rewatching 20+ movies.

TL;DR (short recap)

  • If you want the minimum prep before Thunderbolts*, prioritize: Black Widow, The Falcon and the Winter Soldier, Ant‑Man and the Wasp, Hawkeye, Infinity War, and Endgame.
  • If you have more time and love Bucky, add the Captain America trilogy (especially The Winter Soldier and Civil War).
  • Forum and article discussions mostly agree: this team is all about damaged people trying to redeem themselves, so anything that fleshes out their worst mistakes will make the movie hit harder.
