Tributes have poured in for the Irish-born actor, including one from Ryan Tubridy.
The former host of The Late Late Show previously interviewed the actor.
He shared a picture of the pair together on the set of the iconic chat show.
“The world has just lost a wonderful actor, raconteur and proud Irishman in Michael Gambon,” he wrote.
“Always an entertaining guest and great for a post-show gossip! RIP.”
Michael’s family confirmed the news of his passing this week.
A statement on behalf of his wife and son reads: ‘We are devastated to announce the loss of Michael Gambon.
“Beloved husband and father, Michael died peacefully in hospital with his wife Anne and son Fergus at his bedside, following a bout of pneumonia. Michael was 82.
“We ask that you respect our privacy at this painful time and thank you for your messages of support and love.”
Tributes poured in for the actor after the news was shared of his death.
Emma Watson, who acted alongside him in Harry Potter, wrote: “Kind kind kind Michael Gambon. You never took it too seriously but somehow delivered the most serious moments with all the gravitas.
“Thank you for showing us what it looks like to wear greatness lightly. We will miss you.”
Daniel Radcliffe shared a statement to Variety which read: “With the loss of Michael Gambon the world just became considerably less fun.
“Michael Gambon was one of the most brilliant, effortless actors I’ve ever had the privilege of working with, but despite his immense talent, the thing I will remember most about him is how much fun he had doing his job. He was silly, irreverent and hilarious.
“He loved his job, but never seemed defined by it. He was an incredible story and joke teller and his habit of blurring the lines of fact and fiction when talking to journalists meant that he was also one of the most entertaining people with whom you could ever wish to do a press junket.
“The sixth film was where I got to spend the most time working with Michael and he made the hours spent in front of a green screen together more memorable and joyous than they had any right to be,” Radcliffe added. “I’m so sad to hear he has passed, but I am so grateful for the fact that I am one of the lucky people who got to work with him.”
The Irish actor was born in Cabra in Dublin in 1940.
Over his career, which spanned six decades, he won three Olivier Awards, two Screen Actor Guild Awards and Four BAFTA Awards.
Rest in peace.
