The Story Behind Matt Damon’s Absence From Ben Affleck’s ‘Animals’ Cast

Matt Damon was the first choice to lead ‘Animals’, the crime thriller Ben Affleck directs for Netflix, yet he does not appear in the finished film. The original plan had Damon starring in the movie while Affleck stayed behind the camera. The final arrangement turned out to be quite different.

The story of Matt Damon’s absence from ‘Animals’ involves a late cancellation, a rival kidnapping drama and a calendar that filled up with another major production. The film was set to reach select theaters and Netflix on October 9. Here is how the pieces fell into place.

Matt Damon’s Original Role in ‘Animals’

Damon was originally attached to play Mark Kimball, the lead character. Affleck wanted his close friend in the part after the two described ‘Air’ as the best work experience of their careers. The casting made sense on paper given how often the two have worked together.

The finished film is a crime thriller in which Affleck plays a Los Angeles mayoral candidate whose son is kidnapped. That premise was built around a lead who needed to carry both political pressure and personal panic. Affleck wrote the part with Damon in mind, according to one report on the production.

Damon did not walk away from the project entirely. The film is produced by Artists Equity, the company Affleck and Damon cofounded, so both men serve as producers. His name stayed attached even after his role in front of the camera went elsewhere.

Why Ben Affleck Paused ‘Animals’

The first disruption came well before Damon’s scheduling problems. Affleck told Entertainment Weekly that he pulled the plug on the film just two weeks before shooting was scheduled to begin. At that stage Damon and Jennifer Garner were still the planned leads.

The trigger was a warning that Spike Lee and Denzel Washington were making a film about a kidnapping. That film was ‘Highest 2 Lowest’. Affleck did not want ‘Animals’ to be seen as a competing version.

The concern deepened with further research. Affleck learned that Lee’s movie was a remake of Akira Kurosawa’s ‘High and Low’, and after talking it over with Damon and his producing partners, he stopped the production. The decision was made jointly, which helps explain why Damon remained on the producing side.

Affleck did not give up on the material. He stayed attached because he wanted to use the story to explore economic divides among different communities in Los Angeles. He has said he was disappointed to stop because he had grown interested in making a film about the city.

How the ‘The Odyssey’ Scheduling Conflict Changed the Cast

By the time ‘Animals’ was ready to restart, the calendar had moved on. The delay meant Damon had already committed to Christopher Nolan’s ‘The Odyssey’. Damon was no longer available because he was off shooting another film with Nolan.

Nolan’s film opened on July 17, 2026, and Affleck chose to fill the lead role himself rather than search for another star. The move turned a scheduling problem into a creative one. Affleck now directs, stars and shares writing duties on the project.

Affleck has treated the situation with humor in public. He joked to Entertainment Weekly that Damon had unfortunately chosen a lesser film with ‘The Odyssey’. He also sarcastically suggested that a better actor had to take over the part Damon vacated.

The friendship does not appear to have suffered. The two did get to reunite on another Netflix movie, ‘The Rip’. Damon’s exit from ‘Animals’ reads as a matter of timing rather than a creative disagreement.

Jennifer Garner and the Recast Question

Damon was not the only casting change. Affleck initially wanted Jennifer Garner to play the wife of his character, a therapist in a troubled marriage. He felt she could show something she had not yet had the chance to do in a film.

Accounts of what happened next differ. One report says Kerry Washington took over the role once meant for Garner. Another says Affleck and Garner decided against an on screen pairing to avoid the baggage it could bring. A third describes Garner as worried the pairing would become a distraction.

What is consistent across the coverage is that the film Affleck ended up making is not the one first planned. He now believes ‘Animals’ is different enough from the other kidnapping thrillers to stand on its own. Whether Damon’s version of Mark Kimball would have changed the tone of ‘Animals’, and whether the finished film holds up beside ‘Highest 2 Lowest’, is something viewers who have now watched it are well placed to debate in the comments.
