The Jurassic Park star died on Monday, July 13, in Sydney, Australia, at the age of 78. His family previously described his death as "sudden and unexpected."

Fellow Actor Rima Te Wiata and Ex-Girlfriend Share More Details
Sam Neill’s ex-girlfriend revealed the beloved actor had been seriously ill in the weeks before his death.
Neill's cause of death was first publicly mentioned on Tuesday, July 14, by his Hunt for the Wilderpeople costar, New Zealand actor Rima Te Wiata.
"It really s----, actually," Te Wiata told the New Zealand Herald. "I think he would be like: 'For goodness sake, I got over my cancer. And now look, now I get pneumonia. What next?'"
Neill's ex-girlfriend, Australian journalist Laura Tingle, also spoke about his health during an appearance on "Sydney Mornings."
"So, he’s been pretty sick for the last couple of weeks and everybody who loved him has been willing him on, from near and far. But, I think, it was just a bit too much to recover from one more time," Tingle said.
Years of Cancer Treatment Weakened His Immune System
Sam Neill’s ex-girlfriend revealed years of cancer treatment left the actor with a weakened immune system before his death.
According to Tingle, Neill had undergone extensive chemotherapy and immunotherapy while battling cancer.
"He'd been fighting various forms of cancer for at least the last five years intensively. And that takes a toll on anybody's body," she said, per Entertainment Weekly.
Tingle added that the treatments ultimately weakened Neill's immunity.
She revealed, "He'd had a lot of chemo and a lot of immunotherapy and, thankfully, it had finally cleared him of the blood cancer that he'd had, but it left him pretty compromised in terms of his immune system and I think his poor body sort of got a bit exhausted, as makes sense."
