On the mats we are all equal. It doesn’t matter if you have an Oscar on your mantel or a star on the Walk of Fame, when the round starts, your only currency is your guard and your grit. While many celebrities dabble in the gentle art for movie prep, a select few have stayed long enough to earn the respect of the most cynical practitioners.
As of current, the intersection of Hollywood and BJJ is more crowded than ever. We’ve ranked the top 6 actors and actresses based on their formal rank, their technical legitimacy, and their overall notoriety in both the industry and the academy.
6. Tom Hardy (Brown Belt)
The Tournament Terror
Tom Hardy isn’t just an actor who trains, he’s an actor who actively competes. While most A-listers stick to private celebrity sessions, Hardy made headlines by entering local UK tournaments under his real name, Edward Hardy, and systematically dismantling his divisions.
Promoted to brown belt in early 2026 by Sonny Weston (Horsham BJJ) following a seminar with Tom DeBlass, Hardy’s BJJ notoriety is arguably the highest on this list. He possesses a crushing top game and a legitimate bulldog intensity that mirrors his roles in Warrior and Venom. He isn’t a black belt yet, but in terms of active skill and competitive spirit, he’s a threat to anyone in the Master’s division.
5. Alex O’Loughlin (Black Belt)
The Quiet Killer
The Hawaii Five-0 star is widely known in the BJJ community for being a mat rat. O’Loughlin earned his black belt under Egan Inoue, and unlike many of his peers, he has spent decades quietly putting in the hours. His notoriety might be slightly lower than some of the blockbuster names, but his rank is ironclad. He is often cited by training partners as having a technical, fluid style that reflects a deep, long-term commitment to the art.
4. Ashton Kutcher (Black Belt)
The Modern Milestone
Kutcher’s journey has been one of the most scrutinized in celebrity BJJ. After a decade of training under Master Rigan Machado, Kutcher was promoted to black belt in November 2025. While some internet critics once questioned his rapid rise through the blue and purple belts (thanks to his high-frequency private training), Kutcher has proven his legitimacy through consistent behind the scenes rolling with top-tier athletes. With his background as a high school wrestler from Iowa, his pressure and athleticism make him one of the most formidable celebrity grapplers on the planet.
3. Ed O’Neill (Black Belt)
The OG Of The Arts
Long before BJJ was a global phenomenon, the Modern Family and Married… with Children star was grinding away at the original Gracie Academy in Torrance. O’Neill received his black belt from Rorion Gracie in 2007, a time when getting a black belt as a hobbyist was nearly unheard of. He has often stated that his black belt is his greatest achievement outside of his family. In the BJJ world, O’Neill is royalty, he represents the old school lineage and the patience required to survive 15+ years on the mats.
2. Sean Patrick Flanery (4th Degree Black Belt)
The Technician
If you want to talk about legitimacy, you talk about the Boondock Saints star. Flanery isn’t just a practitioner; he’s an instructor. Holding a 4th-degree black belt under Ricardo Franginha Miller (Paragon BJJ), Flanery is a high-level technician who has competed at the Pan-Ams and won gold at the American Nationals in the lower ranks. He even authored a book, Zane: A BJJ Novel, further cementing his status as a true ambassador of the sport. In a room full of actors, Flanery is the guy most likely to be mistaken for a professional coach, because he is one.
1. Guy Ritchie (3rd Degree Black Belt)
The General
The director of Snatch and The Gentlemen doesn’t just use BJJ in his films, he lives it. Ritchie has been a disciple of Renzo Gracie for over 20 years and currently holds a 3rd-degree black belt. He is famous for having mats on his film sets and inviting cast and crew to roll between takes. Ritchie’s notoriety as a world-class filmmaker, combined with his senior rank under one of the most prestigious lineages in the world, puts him at the top of the food chain. He is the bridge between the grit of the London underground and the prestige of the Hollywood elite.
Honorable Mentions & Rising Stars
- Mario Lopez (Purple Belt): A constant presence on the IBJJF podium, Lopez is a blue-collar practitioner who wins gold at the Master 4 level with impressive consistency.
- Wagner Moura (Brown Belt): The Narcos star was recently promoted to brown belt by Rigan Machado and is known for being a dedicated, high-pressure grappler.
- Sydney Sweeney: While her formal rank is lower than the veterans above, her background in competitive MMA and grappling as a teenager gives her a higher skill floor than almost any other actress in the industry.
