Josh Brolin Says Thanos’ Genocidal Plan in ‘Avengers: Infinity War’ ‘Is Not Necessarily Wrong’

Few Marvel villains have sparked as much genuine debate as Thanos, the purple-skinned warlord whose plan to eliminate half of all life across the universe resonated with audiences rather than evoking pure disgust. Years after ‘Avengers: Endgame’ seemingly wrapped up the character’s arc, the actor behind him continues to find new ways to reignite that discussion.

Josh Brolin, who portrayed Thanos in both ‘Avengers: Infinity War’ and ‘Avengers: Endgame’, has largely remained silent about the character’s potential future in the Marvel Cinematic Universe. However, during recent promotional activities for a different project with a disturbingly similar theme of mass death and survival, he opened up.

While speaking with Collider about ‘The Dog Stars’, his upcoming film with Ridley Scott, the conversation shifted to the possibility of Thanos returning to the MCU. Instead of dismissing the idea, Brolin provided a noncommittal response and offered a more profound reflection on the villain’s worldview.

“I really think the real world has gone off the rails, and I’m beginning to wonder if he was right,” Brolin stated, elaborating on his thoughts. “And then what did Thanos do? He got rid of half the universe in order to save the other half. That was the justification — which is not necessarily wrong,” he shared with Collider, connecting the idea to humanity’s treatment of the planet.

This comparison was not arbitrary. ‘The Dog Stars’ follows a small group of survivors navigating a world ravaged by a deadly virus, with Brolin portraying a hardened protector named Bangley alongside Jacob Elordi’s Hig. The film’s grim, post-apocalyptic backdrop provided Brolin with a clear real-world context to revisit Thanos’ logic, even if he stopped short of endorsing genocide as a viable solution.

Thanos’ rationale has always occupied a peculiar space in blockbuster villainy, presented as coherent enough that entire online communities have formed around the notion that his math, despite its monstrous execution, wasn’t entirely irrational. Brolin’s remarks only add fuel to that ongoing debate, especially as Marvel delves deeper into its next phase of Avengers films.

This isn’t the first time Brolin has hinted that he isn’t done with the role. In a previous conversation on the Happy Sad Confused podcast, he expressed his willingness to reprise the character without hesitation if directors Anthony and Joe Russo reached out, stating he’d be on a plane to London the next day. This openness has kept speculation alive, despite Thanos being definitively killed off when Tony Stark used the Infinity Stones against him at the end of ‘Endgame’.

With ‘Avengers: Doomsday’ currently in production under the Russos, and Marvel increasingly embracing multiverse storytelling that makes death feel less permanent, Brolin’s comments are likely to continue fueling fan theories, regardless of whether Thanos actually returns. For now, his reflections reveal more about how disturbingly relevant the character’s motivations have become.
