The Oscar-nominated star was well known for roles including Quentin Crisp in The Naked Civil Servant, the title role in The Elephant Man and wand merchant Mr Ollivander in the Harry Potter films.
His agent, Charles McDonald, confirmed his death which was on Wednesday, to the Press Association on Saturday.
Earlier this morning (Saturday) his widow, Anwen Hurt, said it will be a “strange world” without him.
She said: “John was the most sublime of actors and the most gentlemanly of gentlemen with the greatest of hearts and the most generosity of spirit. He touched all our lives with joy and magic and it will be a strange world without him.”
Stars who worked alongside Sir John Hurt throughout his 60-year career have also paid tribute to the “magnificent talent” following his death after a battle with cancer.
Welsh actor Luke Evans, who starred alongside Sir John in Hollywood film Immortals in 2011, said he would “never forget” the memories they shared.
He said: “We shared a trailer and we would sit in our loincloths and he would tell me story after story of the good old (crazy!) times of filmmaking.
“I was so new to the business but he spoke to me like an equal, with a kindness and a dignity only a man of his generation possessed.”
He added: “RIP Mr Hurt and thank you for that special memory.”
Oscar-winning American actress Octavia Spencer worked alongside the veteran actor on post-apocalyptic thriller Snowpiercer and recalled similar memories of his storytelling.
She wrote on Instagram: “John Hurt was the craft at its finest.
“It was an honour and a great joy to work with him on Snowpiercer.
“To wile the time away on set, @lucapasqualino #jamieBell #TildaSwinton and I would play a crazy card game.
“Anyway, though John and #ChrisEvans would never play, we’d all convene at our table in base camp and listen to John recount tales of his varied sets throughout the years.
“I was in awe of him because he always looked regal even though we played unwashed rebels in a post apocalyptic film. I can’t explain it. Maybe it was the way he held his cigarette, or that English accent. Or, perhaps the kindness he showed us all allowed his nobility to radiate even beneath the layers of grimey makeup and tattered clothes.
“He was such an interesting man! Miss you, John.”
Actress Clare Higgins, who worked with Sir John on Doctor Who, said he was “the perfect actor” and a “beautiful gentleman”.
Speaking on BBC Breakfast she said he was acknowledged by all actors as one of the “greatest”.
“He was simply the most brilliant complete actor. He gave himself to his role.
“John had a real tenderness and gentleness which is quite rare in a male actor.”
She revealed she had spent three days with Sir John at a Doctor Who convention in Los Angeles last year in one of his last public appearances.
“What was so touching and lovely about John was that this wasn’t an actor talking to fans, this was a person talking to a person.
“It was very moving and lovely to watch.”
Figures from across film, music and sport also remembered the award-winning actor, including Hollywood stalwart Mel Brooks who wrote on Twitter: “It was terribly sad today to learn of John Hurt’s passing. He was a truly magnificent talent.

Hollywood legend Mel Brooks described him as “a truly magnificent talent”.
“No one could have played The Elephant Man more memorably. He carried that film into cinematic immortality. He will be sorely missed,” he added.
Sir John told the Press Association of his diagnosis in June 2015 saying he was optimistic about a satisfactory outcome and continuing to focus on professional commitments.
Sir John enjoyed a big hit with sci-fi horror Alien in 1979 and his character’s final scene has been frequently named as one of the most memorable in cinematic history.
He recently found new fans when he starred as a “forgotten” incarnation of the Doctor, known as the War Doctor, in Doctor Who.
He was knighted by the Queen for services to drama at an investiture ceremony at Windsor Castle in 2015.
Earlier this year Sir John pulled out of a production of John Osborne’s play The Entertainer on medical advice, as he recovered from an intestinal complaint.
He had been due to play Billy Rice in the Kenneth Branagh Theatre Company production, directed by Rob Ashford.
However, he continued to work at a prodigious rate, starring in Jackie Kennedy biopic Jackie, thriller Damascus Cover and the upcoming biopic of boxer Lenny McLean, My Name Is Lenny.
He was also filming Darkest Hour, in which he starred as Neville Chamberlain opposite Gary Oldman’s Winston Churchill.
Sir John, who played Caligula in the celebrated BBC drama I, Claudius, also racked up film hits in V for Vendetta, Indiana Jones and the Kingdom of the Crystal Skull, Tinker Tailor Soldier Spy and Hercules.
Other celebrated roles included his performance as Stephen Ward - a key figure in the Profumo affair - in Scandal and a reprisal of his role as Crisp for An Englishman In New York in 2009, 34 years after his original portrayal of the flamboyant figure.
Sir John’s distinctive voice has been used several times as narrator, and accompanied a chilling Aids awareness advertising campaign in the 1980s.
Born in Chesterfield, Derbyshire, Sir John went to art college before he studied at Rada (Royal Academy of Dramatic Art) and picked up TV and film roles until he had his major breakthrough, appearing in A Man For All Seasons as Richard Rich.
Sir John achieved further prominence in the film 10 Rillington Place as Timothy Evans who was wrongly executed for the crimes of serial killer John Christie, played by Richard Attenborough.
