Lead
On Dec. 25, 2025, A24’s Marty Supreme opened widely in North America, and behind Timothée Chalamet’s convincing on-screen table tennis was a small Pasadena-based team. Diego Schaaf, 71, and his wife Wei Wang, 64, of Alpha Productions were hired in June 2024 to turn Chalamet into a believable elite player for the film directed by Josh Safdie. The couple choreographed matches, sourced period equipment and taught technique so Chalamet could perform both with real balls and with CGI-assisted takes. Their work extended from training sessions in Los Angeles to on-set choreography in New Jersey and a February shoot in Tokyo.
Key Takeaways
- Alpha Productions founders Diego Schaaf (71) and Wei Wang (64) were brought on in June 2024 to prepare Timothée Chalamet for Marty Supreme.
- Chalamet reportedly trained for roughly seven years on and off before this coaching phase, practicing even while filming other projects.
- Schaaf handled match design, period equipment sourcing and background-player coordination across locations including East Rutherford and Tokyo.
- Wang—formerly ranked No. 5 in China and a 1996 U.S. Olympic qualifier—focused on footwork, stroke mechanics and muscle memory during hour-and-a-half sessions.
- Training moved from public clubs to Chalamet’s home to preserve privacy; some scenes required acting to empty air for later CGI insertion.
- The duo recruited 23 professional players for tournament sequences and paid close attention to point development so the action felt cinematic and authentic.
- After the film wrapped, Schaaf and Wang returned to running local clubs in Pasadena and West Los Angeles while remaining open to future film work.
Background
Diego Schaaf and Wei Wang have worked together in Hollywood since the early 1990s, building a niche teaching and choreographing table tennis for film, television and commercials. Operating from Pasadena, the pair run the Westside Table Tennis Center and the Pasadena Table Tennis Club, and their credits include high-profile productions such as Forrest Gump, Friends and Balls of Fury. Their collaboration draws on complementary skills: Schaaf’s production and choreography background and Wang’s elite-level competitive experience.
Wang grew up in Beijing, began playing at age 10 and rose to become one of China’s top players in her era; she later moved to the United States, won U.S. national doubles titles and qualified for the 1996 Olympic team. Schaaf, who learned the sport in Switzerland, transitioned into U.S.-based film and audio work before focusing on table-tennis choreography and production consulting. The couple’s long history in both competition and entertainment positioned them as go-to consultants for filmmakers seeking realism in ping-pong sequences.
Main Event
Josh Safdie’s Marty Supreme required Timothée Chalamet to portray Marty Mauser, a fictionalized mid-century U.S. table tennis star whose arc is driven by a hunt for a world title. Production needed Chalamet to look and move like a top competitor. Schaaf and Wang assessed Chalamet’s baseline abilities in June 2024, decided he had the athletic foundation, and then designed a condensed, intensive program focused on footwork, timing and point structure.
Training sessions typically lasted about 90 minutes when Chalamet was in Los Angeles, held at the couples’ clubs until privacy concerns pushed some work to the actor’s home, where a table was set up on his tennis court. Wang emphasized that top-level table tennis is whole-body movement—footwork, balance and timing—not merely hand skills, and she said Chalamet absorbed those elements quickly. To help the actor internalize sequences, Chalamet named specific points and scenarios so he could distinguish one scripted rally from another during filming.
On set, Schaaf coordinated match choreography for tournament scenes, hiring 23 professional players to populate competition sequences and sourcing authentic 1950s-era equipment for period accuracy. Some takes required Chalamet and others to play without a ball so visual effects teams could add the ball in postproduction; Wang and Schaaf said those silent repetitions were unusually demanding because actors never missed a shot and had to repeat precise motions across many takes. The coaching also extended to Tyler, the Creator, who had to learn basics quickly for his role and reportedly practiced only twice before filming.
Analysis & Implications
The pair’s role on Marty Supreme highlights how small, specialized consultants increasingly shape the realism of sports on film. Producers balancing cinematic rhythm with technical authenticity rely on people who can translate athletic nuance into repeatable, camera-friendly choreography. Schaaf’s production experience and Wang’s competitive pedigree gave Safdie both technical credibility and practical pathways to stage matches that read as real while serving dramatic beats.
For actors, the process demonstrates a trend in method-level physical preparation: sustained, sport-specific training that begins months—or in Chalamet’s case, years—before principal photography. That investment reduces the need for camera tricks and creates performances where viewers perceive genuine skill, which can improve awards visibility and critical reception. It also raises production demands: maintaining consistent technique across long shooting days, accommodating privacy, and coordinating background athletes and VFX teams.
On a broader level, the film’s attention to table-tennis detail may boost public interest in a sport often marginalized in mainstream sports media. Realistic portrayals can translate to increased club participation, more coverage for regional programs, and new commercial opportunities for equipment makers and coaches. For Schaaf and Wang, the project reinforces a sustainable niche—there are relatively few specialists who can combine deep sport knowledge with film-set logistics.

Safdie and producers framed the consultants’ role as central to achieving both period authenticity and dramatic pacing, while background players and crew credited the team with keeping matches performant across long shoots.
Unconfirmed
- Exact cumulative hours Chalamet spent training over the seven-year period reported by media have not been independently verified by Alpha Productions.
- Schaaf’s characterization as the “only” person in the country able to do this work reflects a producer’s remark and should not be read as a verified industry census.
- Specific technical VFX breakdowns for each shot (which effects were practical versus CGI) have not been disclosed publicly by the film’s postproduction team.
Bottom Line
Marty Supreme’s table-tennis scenes demonstrate how focused coaching and choreography can turn an actor into a believable athlete on screen. Diego Schaaf’s production sensibility and Wei Wang’s elite training background combined to keep rallies authentic, aid continuity across many takes and serve the director’s cinematic vision. Their work required balancing period detail, match realism and the unique demands of shooting with and without a physical ball.
Beyond this single film, the project underscores a wider production trend: specialized consultants who bridge sport expertise and on-set requirements are increasingly essential for credible portrayals. For Schaaf and Wang, the film reinforced their niche; for audiences, it may spark renewed interest in table tennis at both recreational and competitive levels.
