The cast of Space Jam: A New Legacy (2021) features a diverse blend of live-action stars and legendary voice talent. NBA icon LeBron James leads the film as a fictionalized version of himself, alongside Don Cheadle as the villainous Al-G Rhythm. Supporting roles include Cedric Joe, Sonequa Martin-Green, and a star-studded voice cast featuring Zendaya as Lola Bunny.
While many audiences originally compared the film to the 1996 original starring Michael Jordan, the 2021 sequel expanded the scope of the "Serververse," incorporating dozens of cameos from the Warner Bros. library. As of 2026, the film remains a significant marker in the transition of NBA superstars into Hollywood anchors. Understanding the cast requires looking at three distinct groups: the live-action family and antagonists, the Looney Tunes voice actors, and the professional athletes who portrayed the "Goon Squad."
The Human Leads: LeBron James and the James Family
At the heart of the film is the relationship between a father and his son. Unlike the original film, which focused more on Michael Jordan’s return to basketball, Space Jam: A New Legacy is a father-son drama wrapped in a high-tech digital adventure.
LeBron James as Himself
LeBron James stepped into the lead role not just as an athlete, but as a producer under his SpringHill Company banner. In the film, James plays a disciplined, "basketball-first" father who struggles to understand his son’s passion for video game design. His performance required significant green-screen interaction, a technical challenge that James handled by drawing on his previous comedic experience in films like Trainwreck (2015). By 2026, his role in this franchise is viewed as a pivotal step in his post-NBA career trajectory in entertainment.
Don Cheadle as Al-G Rhythm
The primary antagonist, Al-G Rhythm, is portrayed by Academy Award nominee Don Cheadle. Al-G is a sentient algorithm living within the Warner 3000 Serververse. Cheadle’s performance is deliberately theatrical, capturing the vanity and insecurity of a computer program that feels underappreciated by its creators. Cheadle brought a level of gravitas to the role, transforming what could have been a generic villain into a nuanced character that represents the pressures of digital relevance.
Cedric Joe as Dominic "Dom" James
Cedric Joe plays LeBron’s middle son, Dom. The character is a talented coder who creates a basketball-themed video game that eventually becomes the setting for the film's climax. Joe’s role is the emotional anchor of the movie; his chemistry with James is what drives the plot forward when Al-G Rhythm manipulates their relationship to lure LeBron into the Serververse.
Sonequa Martin-Green as Kamiyah James
Best known for her roles in Star Trek: Discovery and The Walking Dead, Sonequa Martin-Green plays Kamiyah James, LeBron’s wife. While her role is primarily supportive, she serves as the voice of reason, often mediating the tension between LeBron and Dom. Her presence provides a grounded reality to the otherwise fantastical elements of the movie.
The Voice Cast: Bringing the Looney Tunes to Life
The Looney Tunes are the soul of the Space Jam franchise. For the 2021 sequel, the production utilized a mix of veteran voice actors and high-profile celebrities to modernize the characters.
Zendaya as Lola Bunny
One of the most discussed casting choices was Zendaya as Lola Bunny. The character underwent a significant redesign to move away from the "bombshell" trope of the 1990s, focusing instead on her prowess as a basketball player and her leadership within the squad. Zendaya’s voice performance was intended to give Lola a more authoritative and "cool" persona, aligning with the actress's own public image.
Jeff Bergman as Bugs Bunny, Sylvester, and Yosemite Sam
Jeff Bergman, a veteran who has been voicing Looney Tunes characters since the late 1980s, took on the mantle of Bugs Bunny. Bergman’s task was to maintain the classic "Bugs" wit while adapting to the modern digital setting. He also provided the voices for Sylvester the Cat and Yosemite Sam, showcasing the versatility required of top-tier voice talent.
Eric Bauza as Daffy Duck and Porky Pig
Eric Bauza is often considered the modern heir to Mel Blanc. In A New Legacy, he voiced Daffy Duck—portrayed here as the "coach" of the Tune Squad—as well as Porky Pig, Elmer Fudd, and Foghorn Leghorn. Bauza’s ability to capture the specific stutters and lisps of these iconic characters while delivering rapid-fire dialogue was essential for the film’s pacing.
Gabriel Iglesias and Candi Milo
Comedian Gabriel Iglesias provided the voice for Speedy Gonzales, bringing a high-energy comedic timing to the fastest mouse in Mexico. Meanwhile, Candi Milo voiced Granny, who famously has a standout moment involving a "Matrix-style" combat sequence and a surprising affinity for martinis.
The Goon Squad: Professional Athletes and Their Avatars
Just as the 1996 film featured the "Monstars," A New Legacy features the "Goon Squad"—digitally enhanced versions of real-life NBA and WNBA stars. These actors provided motion capture and voice work for their monstrous counterparts.
| Actor/Athlete | Character Name | Special Abilities |
|---|---|---|
| Klay Thompson | Wet-Fire | Powers of water and fire manipulation |
| Anthony Davis | The Brow | Massive wings and aerial dominance |
| Diana Taurasi | White Mamba | Serpentine movement and speed |
| Nneka Ogwumike | Arachne-neka | Multiple limbs for elite defense |
| Damian Lillard | Chronos | Robotic speed and time-manipulation |
The Significance of the WNBA Inclusion
A major shift in the 2021 cast was the inclusion of WNBA legends Diana Taurasi and Nneka Ogwumike. This reflected the growing cultural prominence of women’s basketball. Taurasi’s "White Mamba" character paid homage to Kobe Bryant’s "Black Mamba" nickname, while Ogwumike’s "Arachne-neka" emphasized the defensive versatility that has defined her career.
Technical Execution and Motion Capture
The casting process for Space Jam: A New Legacy was not limited to traditional acting. Because much of the film takes place in a 3D digital environment, the athletes and live-action stars had to engage in extensive motion capture (mo-cap).
LeBron James and the Goon Squad members spent weeks in specialized suits equipped with sensors. This allowed the animators at Industrial Light & Magic (ILM) to map the athletes' specific movements—such as Anthony Davis’s unique shooting form or Klay Thompson’s perimeter footwork—onto their monstrous avatars. This technical depth ensured that even though the Goon Squad characters looked like mythical creatures, they moved with the authentic cadence of professional basketball players.
Cameos and the Warner Bros. Library
One of the unique "cast" elements of the film is the background audience during the climactic basketball game. The film utilized the concept of the "Serververse" to include hundreds of characters from other franchises.
- The DC Universe: Characters like Batman, Superman, and Wonder Woman are seen in the crowd.
- The Matrix: References to the "Agent" characters and the "Morpheus" choice are central to the early plot.
- Classic Cinema: Characters from Casablanca, The Iron Giant, and A Clockwork Orange make appearances, though these were largely digital recreations or costumed extras rather than the original actors.
One notable "non-cameo" involved Michael Jordan. The film includes a meta-joke where the characters believe they have found Michael Jordan, only for it to be revealed as actor Michael B. Jordan. This clever bit of casting played on audience expectations and served as a passing of the torch.
Production and Direction
The cast was guided by director Malcolm D. Lee, known for The Best Man and Girls Trip. Lee took over the project from Terence Nance, bringing a more comedic and family-oriented focus to the script. The production was also influenced by Ryan Coogler (Black Panther), who served as a producer and contributed to the narrative structure, ensuring that the character arcs for LeBron and Dom were as robust as the visual effects.
Impact of Casting on the Film's Reception
The casting of LeBron James was naturally the film's biggest draw and its biggest point of contention. Critics often compared his "acting" to Michael Jordan's 1996 performance. While Jordan was seen as a charismatic but stoic lead, James was praised by some for his willingness to be the "butt of the joke" and his more expressive emotional range.
The choice of Don Cheadle was almost universally praised. As an actor of his caliber, Cheadle was able to chew the scenery in a way that fit the heightened reality of a cartoon world. His performance as Al-G Rhythm remains one of the most memorable aspects of the 2021 cinematic year.
