Adam Sandler had the lead role in Uncut Gems. Kevin Garnett had never been a professional actor. Yet while filming the Safdie Brothers’ nerve-shredding 2019 thriller, Sandler came away with an almost unbelievable verdict: the NBA legend might actually have been better at acting than he was.
according to a joint interview on Jimmy Kimmel Live!, Adam Sandler reflected on working with Kevin Garnett and admitted that the NBA legend had surprised everyone on set with his natural acting ability. Sandler described Garnett as ‘unbelievably cool’ and ‘super intense,’ adding that the actors on the film were amazed by how naturally Garnett performed, according to Basketball Network.
great guy. Super intense,” Sandler said. “Every actor in the movie was going, ‘Are you kidding me? Kevin Garnett’s better than me at acting?’ He was so smooth and cool every scene he was in,” according to Basketball Network.
That wasn’t empty Hollywood praise.
Sandler was watching Garnett do something that should have been incredibly difficult: walk into a movie packed with experienced performers and completely belong there.
And somehow, the former NBA MVP didn’t just survive.
He stood out.
Adam Sandler and Kevin Garnett Turned Uncut Gems Into a Pressure Cooker
In Uncut Gems, Sandler plays Howard Ratner, a gambling-addicted New York jeweler whose life is constantly one bad decision away from imploding.
Then Kevin Garnett walks into his jewelry store.
Garnett plays a fictionalized version of himself, visiting Howard during the 2012 NBA playoffs. He becomes fascinated by Howard’s rare Ethiopian black opal and starts believing that the stone possesses mystical powers that can help him win.
Howard sees an opportunity to make money.
Garnett sees something much bigger.
That obsession becomes the spark for one of the movie’s most unpredictable relationships.
Howard desperately wants Garnett to return the opal. Garnett doesn’t want to give it up. Every conversation between them feels like a negotiation that could turn ugly at any second.
That’s where Garnett’s real-life personality became an enormous advantage.
He was already famous for being one of basketball’s fiercest competitors. The Safdie Brothers didn’t have to manufacture that intensity.
They just had to point a camera at it.
Garnett Didn’t Play the Role Like a Celebrity Cameo
The biggest danger with casting a professional athlete is obvious: audiences can tell when someone is simply playing themselves.
Garnett avoided that trap.
He didn’t feel like a basketball player visiting a movie set.
He felt like a dangerous, obsessive NBA superstar who had become convinced that a gemstone could change the outcome of his season.
And the Safdie Brothers understood that Garnett had something special before the cameras even rolled.
Josh Safdie told ESPN that the filmmakers initially hesitated when Garnett’s name came up. They agreed to meet him anyway, expecting an hour-long conversation.
It lasted three hours.
Garnett told stories, talked basketball and revealed a side of himself that the filmmakers hadn’t seen through television interviews.
“I would always watch KG postgame because he was so entertaining,” Safdie told ESPN. “But I realized after meeting him that I didn’t know his real voice.”
That meeting changed the casting.
The role had originally been developed with other NBA players in mind, including Amar’e Stoudemire. The Safdies eventually realized Garnett could bring something much more personal to it.
They wrote for his voice.
And it worked.
“He’s Better Than Me”: Sandler Was Genuinely Impressed
Sandler’s comments are particularly striking because Uncut Gems was supposed to be his showcase.
Howard Ratner was one of the most demanding characters of Sandler’s career.
The performance was frantic, desperate and emotionally exhausting. It was also a dramatic turn that reminded audiences Sandler could do much more than comedy.
But while Sandler was fighting his way through Howard’s chaos, Garnett was quietly making his own mark.
Sandler remembered the other actors being stunned by him.
“Are you kidding me? Kevin Garnett’s better than me at acting?” they reportedly asked.
Sandler’s response was essentially yes.
“He was so smooth and cool every scene he was in,” Sandler said.
That humility says a lot about Sandler.
He wasn’t protecting his ego.
He was giving Garnett credit.
And after watching the movie, it’s difficult to argue with him.
Kevin Garnett Prepared for Acting Like He Prepared for the NBA
Garnett’s performance wasn’t completely accidental.
He approached the movie with the same obsessive preparation that had defined his basketball career.
In an interview with ESPN, Garnett explained his philosophy bluntly: “Acting is preparation, just like anything else.”
He added, “I didn’t want to fail them. They took a risk on me. When I showed up to set, I was ready.”
That mindset sounds remarkably similar to the way Garnett approached opponents.
Before a game, he studied them.
He watched film.
He learned tendencies.
He looked for weaknesses.
For Uncut Gems, he applied that same mentality to acting.
“It took me back to, ‘OK, it’s Rasheed Wallace tonight. It’s Tim Duncan tonight’ — watching film. I took those same things coming in here,” Garnett explained.
In other words, Garnett didn’t treat the movie like a vacation from basketball.
He treated it like another competition.
The Safdie Brothers Let Garnett Bring His Real Intensity
That’s one of the reasons his performance feels so different from the usual athlete cameo.
Garnett’s character isn’t polished.
He’s obsessive.
He’s superstitious.
He’s intimidating.
He’s funny one moment and unsettling the next.
Those qualities were already part of Garnett’s public persona, so the Safdies didn’t need to create them from scratch.
They needed to channel them.
Josh Safdie told ESPN that Garnett took his lines seriously and added some flair of his own, while still sticking mostly to the script.
That balance was crucial.
Garnett could improvise without destroying the realism.
He could intimidate without overplaying the scene.
And most importantly, he could make Howard feel like the smaller man in the room.
That’s no small achievement when Howard is being played by Adam Sandler.
Why Athletes Can Sometimes Surprise Hollywood Directors
Garnett’s performance isn’t proof that every athlete can act.
But it does show why elite athletes can sometimes possess qualities that translate beautifully to the screen.
1. They Already Know What Pressure Feels Like
Elite athletes spend their careers performing with enormous expectations hanging over them.
They know what it’s like to have thousands of people watching every mistake.
Garnett didn’t have to learn how to project pressure.
He had lived inside it for years.
2. They Know How to Read Their Opponent
Basketball requires constant observation.
Players study body language, tendencies and reactions.
That translates surprisingly well to acting because great screen performances aren’t only about delivering lines.
They’re about listening and reacting.
Garnett did both.
3. They Understand Commitment
At the professional level, hesitation can cost you.
Garnett brought that same commitment to Uncut Gems.
He didn’t play the character with a wink.
He didn’t constantly remind the audience that he was Kevin Garnett.
He committed to the idea that the opal mattered.
Once he did that, the audience could believe it too.
The Black Opal Was Ridiculous—Until Garnett Made It Feel Real
On paper, the idea sounds almost absurd.
An NBA superstar becomes convinced that a black opal possesses mystical powers.
But Uncut Gems never plays the premise like a joke.
Garnett’s belief gives the stone weight.
His obsession drives the story.
And because Garnett approaches the situation with the seriousness of a playoff game, Howard’s increasingly desperate attempts to control the situation become even more chaotic.
That’s the genius of the casting.
Garnett’s basketball mentality becomes part of the movie’s psychology.
He wants to win.
Howard wants to profit.
Neither man knows how to walk away.
And that’s exactly the kind of combustible relationship the Safdies wanted.
Sandler Was the Star. Garnett Became the Wild Card.
There’s an irony buried inside Sandler’s compliment.
Howard Ratner is a character who believes he can outsmart everybody.
He thinks he can manipulate Garnett.
He thinks he can beat the odds.
He thinks one more gamble will solve everything.
Sandler, meanwhile, had no problem admitting that his co-star had surprised him.
That’s a very different kind of confidence.
Instead of trying to diminish Garnett’s contribution, Sandler celebrated it.
And Garnett earned that respect.
The Safdie Brothers had taken a huge gamble by putting a retired NBA superstar into one of the most intense independent films of the decade.
It paid off.
Kevin Garnett’s Uncut Gems Performance Still Feels Like a Gamble That Worked
Uncut Gems was built around impossible risks.
Howard risks his money.
He risks his marriage.
He risks his business.
He risks his life.
The Safdie Brothers took their own risk by giving a major role to someone whose résumé had almost nothing to do with acting.
Kevin Garnett made that gamble look easy.
He brought the competitiveness of an NBA superstar, the confidence of a veteran performer and the unpredictability of someone who didn’t seem afraid of the camera.
And Adam Sandler noticed.
Years after the film’s release, his assessment remains one of the most entertaining compliments an actor could receive from another actor:
“He’s better than me at acting.”
For a movie about ego, obsession and the desperate need to win, there may be no more fitting compliment.
Kevin Garnett didn’t just show up in Uncut Gems.
He competed.
And apparently, even Adam Sandler thought he won.
