Actor Sam Neill has revealed he is being treated for stage three blood cancer, writing in a memoir that he was "possibly dying" from the illness diagnosed a year ago.

The New Zealander, who became famous after starring as Dr Alan Grant in the 1993 blockbuster Jurassic Park, said he began treatment last March for non-Hodgkin lymphoma.

Neill, 75, makes the revelation in his book Did I Ever Tell You This?, which is being released next week.

In the opening chapter, written while undergoing chemotherapy, Neill said: "The thing is, I'm crook. Possibly dying. I may have to speed this up."

The actor told The Guardian he is now in remission but will continue to undergo chemotherapy for the remainder of his life.

"I can't pretend that the last year hasn't had its dark moments," he said.

"But those dark moments throw the light into sharp relief, you know, and have made me grateful for every day and immensely grateful for all my friends. Just pleased to be alive."

Neill's acting career began in the 1970s and has spanned dozens of roles in TV and film, including Peaky Blinders, The Hunt for Red October and The Piano.

He is currently preparing for a role in a television adaptation of Liane Moriarty's best-selling novel Apples Never Fall, which will be filmed in Australia.

When he's not acting, Neill also runs vineyards in the picturesque Central Otago region of New Zealand's South Island.
