Sam Neill’s Cause of Death: Pneumonia Confirmed by Agent
Sam Neill, the beloved New Zealand actor best known for his role as Dr. Alan Grant in the “Jurassic Park” franchise, died from pneumonia at the age of 78, his representative confirmed on Thursday. The disclosure was issued to correct what the agent described as “inaccuracies and outright falsehoods” in media reporting following the actor’s death earlier this week.
Neill passed away on July 13 at St. Vincent’s Private Hospital in Sydney, Australia, surrounded by family. His death came as a shock to fans worldwide, particularly given that he had announced he was cancer-free just three months prior after a successful battle with angioimmunoblastic T-cell lymphoma.
Agent Confirms Cause of Death
Philip Grenz, Neill’s agent of 19 years, released a statement to Page Six clarifying the circumstances of the actor’s death.
“Sam passed away from pneumonia,” Grenz said. “Prior to becoming sick, Sam had valiantly fought and beaten lymphoma through a new treatment called CAR-T therapy.”
Grenz said he disclosed the details after consulting with Neill’s family and following news reports “which contain inaccuracies and outright falsehoods.” The agent added that Neill had completed four projects “back-to-back” over the past year that are expected to be released in the coming months.
“As Sam was an intensely private man who loathed a fuss, his family will honor him with a private family memorial at his farm in New Zealand at a still-undetermined later date,” Grenz said, according to Fox News.
A Remarkable Cancer Battle
Neill was diagnosed with angioimmunoblastic T-cell lymphoma, a rare form of non-Hodgkin lymphoma, in 2022. After years of chemotherapy, he participated in a successful clinical trial for CAR T-cell therapy (chimeric antigen receptor T-cell therapy), a form of cancer immunotherapy that reprograms a patient’s own immune cells to attack cancer cells.
In April 2026, just three months before his death, Neill announced he was cancer-free. “I’ve just had a scan just now and there is no cancer in my body. That’s an extraordinary thing,” he told Australian network 7News at the time. “I’m very, very excited that this can happen.”
However, multiple sources noted that Neill’s immune system was compromised after years of intensive cancer treatment, leaving him more vulnerable to infections like pneumonia. Laura Tingle, his former partner and an ABC journalist, told The Guardian that the intensive treatment “left him pretty compromised in terms of his immune system.”
Tributes Pour In From Hollywood
Following Neill’s death, an outpouring of tributes came from co-stars and directors who worked with him over his five-decade career.
Steven Spielberg, who directed Neill as paleontologist Dr. Alan Grant in the 1993 blockbuster “Jurassic Park,” said the actor would never be forgotten. “I adored making all the Jurassic movies with him,” Spielberg said. “Along with Laura Dern and Jeff Goldblum, we will always have our Jurassic family and Sam will never be forgotten by us or his many millions of fans around the world.”
Laura Dern called Neill “my beloved lifetime friend,” adding: “He showed me the depths of loyalty, protectiveness and love always with the driest of wit.” Jeff Goldblum wrote simply: “The next great adventure begins. Love, always and forever.”
Nicole Kidman, who starred alongside Neill in the 1989 thriller “Dead Calm,” remembered him as “one of the greats. A joy to be around.” She added: “We met when I was just 18, and he took me under his wing and we stayed friends for life. He was charming, kind, funny, and intelligent.”
Cillian Murphy, who worked with Neill on “Peaky Blinders,” told Page Six he “admired and adored [Neill] in equal measure.”
Rima Te Wiata, Neill’s co-star from “Hunt for the Wilderpeople,” captured the tragic irony of his passing. “It really sucks actually,” she said. “I think he would be like: ‘For goodness sake, I got over my cancer. And now look, now I get pneumonia. What next?’”
A Legacy Across Five Decades
Born Nigel John Dermot Neill in Northern Ireland in 1947, Neill moved to New Zealand with his family as a child. His breakout role came in the 1977 thriller “Sleeping Dogs,” and over a career spanning more than five decades, he amassed over 150 film and television credits.
His most iconic role was as Dr. Alan Grant in “Jurassic Park” (1993), a performance that made him a household name. He returned for “Jurassic Park III” and reunited with Dern and Goldblum for 2022’s “Jurassic World Dominion.” His other notable works included “The Hunt for Red October,” “The Piano,” “Event Horizon,” “The Horse Whisperer,” “Peaky Blinders,” “The Tudors,” and “Merlin.”
When not acting, Neill spent much of his time at Two Paddocks, his boutique vineyard in New Zealand’s Central Otago region, where he produced pinot noir and riesling wines. He was knighted in New Zealand and is survived by four children and eight grandchildren.
A private family memorial will be held at his New Zealand farm at a later date.
