McDonald offered no other details of Hurt's passing.
Known for playing tormented characters, Hurt memorably died on screen in the 1979 space adventure "Alien
" when a creature exploded from his chest during lunch in the spacecraft mess hall. CNN's "The Screening Room" in 2007 ranked it among its Top 10 favorite movie deaths.
Hurt always stayed busy, working more than six decades in television, movies and voice work in England and the United States. He recently played a priest who counsels Jacqueline Kennedy in last year's biopic "Jackie," according to IMDb.
"I'm very much of the opinion that to work is better than not to work," he said, according to his IMDb bio. "There are others who'd say, 'No, wait around for the right thing' - and they will finish up a purer animal than me. ... Of course, I don't do everything by any means: I do turn lots of stuff down, because it's absolute crap. But I usually find something interesting enough to do."
Accolades poured in on social media.
Actor Kiefer Sutherland tweeted: "My deepest sympathies to John Hurt's family, friends and fans. He was a dear friend."
Actor Elijah Wood tweeted: "Very sad to hear of John Hurt's passing. It was such an honor to have watched you work, sir."
Hurt was born in Shirebrook, a coal mining village in Derbyshire, England, the son of an an engineer and one-time actress and an Anglican clergyman and mathematician, IMDb said.
He trained to become a painter but, after being accepted into the Royal Academy of Dramatic Art, worked on the stage in the early 1960s.
His first film role came in the "angry young man" drama "Young and Willing" in 1962 and his first major role in "A Man for All Seasons" in 1966, IMDb said.
His big break came when he portrayed the gay writer and raconteur Quentin Crisp in the mid-1970s television play "The Naked Civil Servant," which was adapted from Crisp's autobiography, IMDb said.
The good roles kept coming. He went on to play a Turkish prison inmate in "Midnight Express" in 1978 and the gentle, disfigured John Merrick in "The Elephant Man" in 1980. Those roles earned him Oscar nominations and he won a Golden Globe for best supporting actor in "Midnight Express."
He usually played characters with problems, and IMDb said he died 47 times on screen. But Hurt also also had comic roles, such as Jesus in Mel Brooks' "History of the World: Part I" in 1981, which he took on because he'd just done two serious roles and wanted to have some fun, IMDb said.
Hurt appeared in the first two Harry Potter movies, playing wand maker Garrick Ollivander, and did voice work and narration in movies like "Watership Down," "The Plague Dogs," and "Thumbelina."
Some of his top television roles included Caligula in "I, Claudius" in 1976, General Woundwort in "Watership Down" and the War Doctor in "Doctor Who."
He was awarded the CBE (Commander of the Order of the British Empire) in the 2004 Queen's Birthday Honours List for his services to Drama.
Hurt was married four times and was married to Anwen Rees-Myers when he died. Hurt was an alcoholic for years but said he quit drinking in 2005, according to IMDb.
A grand scheme never guided his life, he said.
"I've just been whipped along by the waves I'm sitting in," he said, according to IMDb. "I don't make plans at all. Plans are what make God laugh. You can make plans, you can make so many plans, but they never go right, do they?"
