Marty Supreme Cast Guide: All the Surprising Cameos and Supporting Players Joining Timothée Chalamet

A24’s buzzy new sports dramedy Marty Supreme is already generating major awards chatter — and not just because Timothée Chalamet steps into the shoes of real-life ping pong legend Marty Reisman. The film is packed with unexpected cameos, dramatized eccentric personalities, and a roster of supporting players drawn straight from the ping pong subculture that shaped Reisman’s world.

A Wild Origin Story Behind the Film

Before he became an acclaimed playwright and filmmaker, David Mamet had a very different hustle. In college, Mamet and his friend — comedian and table tennis champion Jonathan Katz — would run a clever con by betting on matches where Mamet, the weaker player, would unexpectedly win. Years later, Mamet became a regular at Marty Reisman’s famed Upper West Side table tennis club, a den for hustlers, eccentrics, and big-name patrons including Dustin Hoffman and Matthew Broderick.

That real-world circle helps form the backbone of Marty Supreme, which blends fact and fiction as it traces Reisman’s swagger, showmanship, and once-in-a-generation talent.

David Mamet Joins the Cast as Glen Nordmann

In a meta twist, Mamet appears in the film as Glen Nordmann, the no-nonsense director overseeing a stage production starring Gwyneth Paltrow’s character, Kay Stone — a washed-up actress hunting for one last comeback. Mamet’s dry, clipped delivery gives Nordmann a comedic edge, while also nodding to his real-life friendship with Reisman and Katz.

Celebrity Cameos and Supporting Stars

While Chalamet carries the film with a charismatic performance as Reisman — all bravado, fast hands, and 1950s showman flair — the supporting cast adds layers of oddball charm:

• Jonathan Katz appears as a fictionalized version of himself, leaning into his history with Mamet and the world of hustlers
• A handful of real-world table tennis champions make brief appearances, including former pros who once trained or played with Reisman
• Cameos from New York theater icons echo the era when Reisman’s gym doubled as an unofficial clubhouse for actors and artists

The result is a film that recreates a vibrant city ecosystem — part sports hall, part gambling den, part performance stage — that shaped Reisman’s mythic persona.

A24’s Growing Awards Contender

Marty Supreme broke records for A24 with its limited-release box office debut, and early reactions highlight Chalamet’s performance alongside the film’s nostalgic portrait of 1970s New York counterculture. The mix of real history, eccentric personalities, and celebrity cameos gives the film an energy that feels both chaotic and deeply authentic.

As the awards season heats up, Marty Supreme looks increasingly like a major contender, thanks in part to the eclectic cast surrounding its magnetic leading man.
