Jason Clarke is opening up about the intense physical and psychological toll of playing convicted murderer Alex Murdaugh in Hulu’s true-crime miniseries Murdaugh: Death in the Family, revealing just how far he went to embody the disgraced South Carolina attorney.
Speaking with TV Insider in an interview published Wednesday, November 19, Clarke said it “took a lot” to step into Murdaugh’s mindset and presence over the course of the eight-episode series. The actor, who received strong notices for the performance, emphasized that the role demanded a transformation far beyond prosthetics and styling.
Asked what he learned about Murdaugh while portraying him, Clarke pointed to the figure’s unrelenting drive, even in the face of national scrutiny and legal consequences. “I learned, I guess, his strength. His monumental, Clydesdale horse [conviction]. I mean, the man has not buckled. In his own way, he’s wavered, he’s learned, he’s been through great humiliation. He’s been through great horror,” Clarke said.
Clarke added that the sheer force of Murdaugh’s will — and the way it persists — was a key part of finding the character. He described Murdaugh’s demeanor as a kind of unwavering constitution that continues to propel him forward, regardless of consequences or public exposure.
In June 2021, Murdaugh fatally shot his wife, Maggie, and their son, Paul, with an AR-style rifle. He was later arrested and found guilty of their murders, and separate investigations uncovered that he had stolen $12 million from his law firm. Hulu’s miniseries charts the rise and collapse of the once-powerful legal scion and the devastating impact on the community around him.
The Physical Transformation Was Exhausting
Beyond the psychological demands, Clarke underwent a major physical transformation to approximate Murdaugh’s look and presence on screen. He gained 40 pounds for the role, wore a wig, and dyed his eyebrows — details he says were crucial to capturing the character’s outward image.
“And I learned playing him — with that much weight on me, on my frame… I was so bloated, and having to consume so many things or having to not consume certain things when I was drying out the last two episodes myself, in terms of food — it took a lot to be him, to play him,” Clarke said. “It was exhausting being him.”
Clarke explained that the physical changes influenced the way he moved and held himself, contributing to a more authentic portrayal. That immersion, though, came with a cost. “Just entertaining, dominating me. Daddy’s dying, but me. All the time, me. It was exhausting,” he added, describing the character’s relentless self-focus as an energy he had to constantly calibrate during production.
The combination of weight, styling, and the character’s persistent inner engine made the performance one of the most demanding of Clarke’s career — a challenge that he says was essential to understanding how Murdaugh navigated both private turmoil and public collapse.
Inside The Murders: Clarke’s “Shark” Perspective
Clarke also discussed his approach to one of the series’ most difficult sequences, depicting the night Maggie (played by Patricia Arquette) and Paul (Johnny Berchtold) were killed. He crafted Murdaugh’s inner life around a single, driving metaphor: motion without pause.
“I always thought [Alex] was a shark. The minute he stops swimming, he’ll have to die,” Clarke said. “I wanted that in the death scene, when you see his side of shooting, there’s that one moment where he locked the gun, and he hears Paul moaning, that he could have blown his own [head off], and maybe for a split second [he considered], and he said, ‘No.'”
According to Clarke, that moment becomes the pivot point for the character’s resolve: “He’s got the gumption to rack it and turn around, and Paul surprises him, and, bang, gives him a second one, which builds the strength to do Maggie, quite simply.”
For Clarke, that unbroken forward momentum — however monstrous — was central to portraying Murdaugh’s psyche. “There’s something about these fires that he walked through that hardened him,” he said, noting how repeated crises seemed to fortify rather than break the man he was depicting.
Where To Watch Murdaugh: Death in the Family
All eight episodes of Murdaugh: Death in the Family are now streaming on Hulu. The limited series traces the Murdaugh family’s unraveling, from the high-profile investigations to the courtroom revelations that exposed years of financial crimes and addiction struggles alongside the murders of Maggie and Paul.
Clarke’s turn anchors the show, which balances procedural detail with an intimate look at how a prominent Southern dynasty came apart. With a surrounding ensemble that includes Patricia Arquette and Johnny Berchtold, the miniseries offers a stark, character-driven examination of power, denial, and downfall.
For Clarke, the role demanded a full-spectrum commitment that extended from the surface — weight gain and hair work — to the most unsettling corners of Murdaugh’s interior life. Whether studying court footage or calibrating the character’s relentless forward motion, he aimed to depict a man who refused to stop swimming, even as the tide turned irrevocably against him.
“It took a lot to be him, to play him,” Clarke said. That rigor — physical, mental, and emotional — is built into every frame of the Hulu series, illuminating not just what happened, but how someone like Alex Murdaugh kept moving until there was nowhere left to go.
