Matt Damon helped convince Ben Affleck to walk away from Batman and the DCEU

Ben Affleck did not bail on Batman on a whim. He walked away after a rough stretch on Justice League and a nudge from the one guy who can actually talk him into rethinking his career: Matt Damon.

The moment that flipped the switch

Affleck first suited up in 2016 as a seasoned, beat-up Bruce Wayne in the DC Extended Universe, and a lot of folks liked the harder-edged angle he brought to the role. He popped up in several DC movies after that, but the whole run was rocky: backstage drama, shifting creative plans, and nonstop questions about whether he was staying or going.

In 2022, speaking to Entertainment Weekly, Affleck said the troubled Justice League shoot was the turning point. Damon urged him to be choosier and chase projects that actually felt worth doing. Affleck realized he did not want to repeat an experience that left him drained on both the creative and personal fronts.

"But really what it was is that I wasn't happy. I didn't like being there."

In that same interview, he called Justice League the lowest stretch of his career for a mix of reasons. He did not pin it on any one person, but said the job stopped being creatively interesting and came with some genuinely unpleasant moments. That is when he decided he did not want to keep doing it, period.

He talked it through with Damon and credits that conversation with helping him pivot. What he needed were movies that made him happy. He points to The Last Duel as the reset: he plays a pretty awful villain, he is not the lead, and he loved the experience because he was no longer chasing what other people expected of him.

Why Damon matters here

Affleck and Damon go way back. They grew up together in Cambridge, Massachusetts, acted together as kids, and then detonated Hollywood with Good Will Hunting in 1997, which they co-wrote and starred in. That script won them the Oscar for Best Original Screenplay and set both careers in motion. Over the years they have leaned on each other for blunt notes and real support, especially when things get messy.

The partnership did not end with Good Will Hunting. They have kept finding ways to work together, often preferring to team up instead of compete. Most recently, Air became the first release from their production company, Artists Equity, another sign they are building long-term instead of chasing one-offs.

• Good Will Hunting (1997) — co-writers and stars; won the Academy Award for Best Original Screenplay
• Dogma ( 1999)
• Jay and Silent Bob Strike Back (2001)
• The Last Duel (2021)
• Air (2023) — first film from their company, Artists Equity

So when Affleck says Damon pushed him to rethink Batman after Justice League, that tracks with how they have always operated: candid conversations that steer big choices and, in this case, helped Affleck shift toward projects that actually make him want to show up to set.
