Sam Neill, the acclaimed New Zealand actor known for roles in Jurassic Park and The Piano, has died at age 78. He passed away Monday in Sydney, Australia, according to a statement shared on his Instagram account by his family.

Neill had recently revealed he was cancer-free following a diagnosis of stage three angioimmunoblastic T-cell lymphoma, a type of blood cancer, in 2022. The family statement indicated his death was sudden and unexpected, noting that Neill remained cancer-free at the time of his passing. His family expressed gratitude to the staff at St Vincent's Private hospital for their care.

Neill was born Nigel John Dermot Neill in 1947 in Omagh, Northern Ireland, to an English mother and a New Zealand father serving in the British army. The family moved to New Zealand in 1954. He adopted the name Sam at age 12 because he felt it helped him move more easily through the world.

After initially studying law at Canterbury University, Neill turned to acting and joined the Downstage Theatre in Wellington as a professional actor. His breakout role came in 1977 with the film Sleeping Dogs, the first New Zealand film to open in the United States.

Neill's international career flourished throughout the 1980s and 1990s. He appeared in films including My Brilliant Career, Omen III, Possession, Evil Angels opposite Meryl Streep, and The Hunt for Red October. He gained widespread recognition in 1993 with two major roles: as settler Alisdair Stewart in Jane Campion's Oscar-winning film The Piano, and as Dr. Alan Grant in Steven Spielberg's Jurassic Park, a role originally offered to Harrison Ford. He reprised the role in two sequels.

Over five decades, Neill accumulated more than 150 credits in both film and television. His diverse filmography included Dead Calm, The Jungle Book, Event Horizon, and Bicentennial Man. In television, he played corrupt officer Maj Chester Campbell in the series Peaky Blinders and received a Golden Globe nomination for his portrayal of spy Sidney Reilly in 1983.

In 2016, Neill starred in Taika Waititi's hit film Hunt for the Wilderpeople, leading to cameo appearances in subsequent Thor films. He was considered a leading candidate to replace Roger Moore as James Bond and completed a screen test in 1986, though Timothy Dalton ultimately won the role.

Neill lived on a winery called Two Paddocks in Central Otago, New Zealand. In 2023, he revealed in his memoir Did I Ever Tell You This? that he had undergone chemotherapy for a year following his cancer diagnosis. By the time his book was published, his cancer had entered remission, though he continued monthly chemotherapy treatments for the rest of his life.
