Sir Michael Gambon's cause of death has been revealed after it was announced that the star had passed away earlier today.
In a statement issued on behalf of his wife, Lady Anne Gambon, and son Fergus Gambon, the family revealed the 82-year-old's cause of death.
"We are devastated to announce the loss of Sir Michael Gambon," they wrote, as per the Independent. "Beloved husband and father, Michael died peacefully in hospital with his wife Anne and son Fergus at his bedside, following a bout of pneumonia."
While Gambon starred in many movies and TV series, one of his most famous roles that garnered him a lot of fans was none other than his iconic portrayal of Albus Dumbledore in the Harry Potter franchise after the original actor Richard Harris passed away.
And unsurprisingly, his fellow co-stars from the series led the tributes to the well-loved veteran entertainer.
James Phelps - who played Fred Weasley in the franchise - took to X (formerly known as Twitter), to post a touching anecdote about the kindness of Gambon alongside the caption: "Very sorry to hear about the passing of Michael Gambon. He was, on and off the camera, a legend. Just a little memory of Michael."
In the screenshot of the memory, he recalled: "Whilst shooting HP6 I worked on the AD department for the whole shoot (apart from the days I was acting). And for that reason I spent many hours with Michael during the shoot. He was always very funny and very welcoming to share any knowledge he had.
Phelps continued: "One day we were shooting Dumbledore's final clock tower scene, obviously quite an intense scene. In between se ups, Michael asked what I was up to that weekend. As it happened my brother and I were reading Peter and the Wolf with the Manchester Halle orchestra. 'Do you have the script with you?' He asked."
Phelps then said that Gambon offered to help him rehearse so he could give him a few tips.
"So we spent what should have been his downtime going over my weekend gig. It is a memory I've always had as one of the highlights of my HP days," he concluded.
Jason Isaacs, who portrayed the Death Eater Lucius Malfoy on Harry Potter, also had some kind words to offer about the late actor.
"Magnificent Michael Gambon has died," he wrote on X. "I learned what acting could be from Michael in The Singing Detective - complex, vulnerable and utterly human. The greatest thrill of being in the Potter films was that he knew my name and shared his fearless, filthy sense of fun with me."
Fiona Shaw, who played Petunia Dursley in the HP films, referred to Gambon as a "magnificent trickster" and gushed that he could "do anything."
"I will remember him because he was also a gun maker, he could he could make guns, he always said he could fool the V&A into believing that they were 18th century guns," she said during an interview on BBC Radio 4's The World at One. "So I will think of him as a trickster, just brilliant, magnificent trickster, but with text, there was nothing like him, he could do anything."
She also said of working with him on the set of Harry Potter saying: "He took over from Richard Harris and of course, he began to mimic Richard Harris, who had recently died, and he would do his accent, the slight Irish accent."
His other work included stints on The Cook, the Thief, His Wife & Her Lover (1989), Gosford Park (2001), and The King's Speech (2010). Off the big screen, he also worked on the popular series The Singing Detective (1986) as well as on stage in a rendition 1962 production of Othello in Dublin, Ireland.
It is clear that the 82-year-old was truly loved by his friends, his colleagues, and his fans.
Our thoughts and prayers are with his family and loved ones during this difficult time.
