More about Marty Supreme

Variety reported on September 2024 that Marty Supreme is a film centered around professional table tennis. The film, directed by Josh Safdie and produced by A24, has added multiple cast members, including Odessa A’zion, magician Penn Jillette, filmmaker Abel Ferrara, and Shark Tank fame Kevin O’Leary. However, the studio has maintained secrecy around character details.

The film is scheduled for release in the United States on December 25, 2025. After initial reports surfaced, A24 studio posted an image on X, on July 16, 2024, featuring a ping pong ball with the words “coming soon."

Timothée Chalamet joined Marty Supreme in July 2024, with Josh Safdie directing and co-writing the script with Ronald Bronstein. Initial reports suggested that the film was inspired by professional table tennis player Marty Reisman. However, sources close to the production told Deadline in November last year that it's a "fictionalized original" rather than a biopic.

In an October 2024 report by People magazine, Chalamet was seen filming for this project with mustache and glasses. During a conversation with Theo Von on This Past Weekend podcast, released on December 16, 2024, Chalamet discussed his preparation for the role, stating that Safdie encouraged him to perform some of his stunts.

In the same interview, the actor shared that for the table tennis scenes in the film, he trained with former professional players Diego Schaaf and Wei Wang.

According to Deadline Hollywood, the film’s budget is estimated at $70 million, making it A24’s most expensive production to date, surpassing Civil War (2024), which had a budget of $50 million.
