Sir Michael Gambon’s heartbreaking favourite Dumbledore line is ‘giving people goosebumps’

The eight-part Harry Potter franchise gave us many memorable moments and iconic quotes, but we all have our favourites.

So do the star-studded cast who got to say them - but the late Sir Michael Gambon's has got to be the most heartwarming.

The actor, 82, had a massive impact on the wizarding series and basically became our on-screen grandad - offering words of wisdom and some worldly knowledge that didn't just apply when you're trying to defeat Lord Voldemort.

His character, Professor Albus Dumbledore, was a central part of the plot, guiding Harry (Daniel Radcliffe) through his teen years and gearing him up to take on the Dark Lord.

But despite his years of mentoring The Boy Who Lived, Sir Michael's favourite film moment that they shared wasn't when they foiled the plot of the fake Mad Eye Moody together or faced off with Death Eaters.

In fact, the moment he remembers most fondly is when he uttered just one word to his co-star.

Back in 2011, just before the final film to complete the magical franchise was released around the world, the cast of the series all shared their most memorable quotes from their ten years of working together.

For Julie Walters, aka family matriarch Molly Weasley, she revelled in the memory of delivering the iconic line to Bellatrix Lestrange (Helena Bonham Carter): "Not my daughter you b*tch!"

She said of the scene: "So incongruous, I couldn't believe Mrs Weasley said it when I read that. It was fabulous to say."

The late Robbie Coltrane, who starred as friendly giant Hagrid, said his was the moment in Harry Potter and the Philosopher's Stone where he informs the young wizard: "You're Harry Potter. You're the one who got away from.... You Know Who."

But just as he stole scenes, Sir Michael managed to steal the show when he shared his favourite line from Harry Potter.

The Churchill's Secret star said: "Well, I hardly ever knew my lines in the film anyway. But my favourite line, is when I appear as a ghost on the station platform.

"And I say, 'Harry...' And I felt like crying. That's my favourite one."

If you're not an avid Potterhead, here's a quick rundown on the poignant scene Dumbledore shared with Harry.

Voldemort had just seemingly killed The Chosen One in the Forbidden Forest - but all was not as it seemed.

When the noseless villain killed his parents, Lily and James Potter, all those years ago, his curse rebounded on him and a piece of his mangled soul latched itself onto Harry - meaning the teen had become a Horcrux.

If Harry wanted to stop the Dark Lord once and for all, he would have to die.

After Voldemort casts the Killing Curse, Harry wakes up in limbo and he's greeted by Dumbledore on a bright, white train platform, who gently utters: "Harry...you wonderful boy. You brave man. Let us walk."

They had a deep chat while stuck in the eerie purgatory, before Harry is given the choice to return to the land of the living or metaphorically 'board the train' with Dumbledore and join him in the afterlife. As we know, he chose to return.

It's such a moving moment and it clearly stuck with Sir Michael after the filming had finished - as well as a host of Harry Potter fans who took to social media to share their thoughts.

One said: "Hearing Dumbledore's gave me instant goosebumps."

Another wrote: "Dumbledore saying 'Harry' is so comforting," while a third added: "He said 'Harry' and I started SOBBING."

And a fourth wrote: "Michael Gambon was such a treasure. He was phenomenal and so true to his character. RIP."

I second that.
