The world lost some of its most iconic celebrities in 2016, including ​Carrie Fisher and David Bowie. For ​Harry Potterfans, the January 14, 2016 death of ​Alan Rickman hit hard. Unsurprisingly, his castmates were also deeply impacted by the actor's death and have spoken out several times over the years about the magic he brought to the set.

"Alan Rickman is undoubtedly one of the greatest actors I will ever work with," ​Daniel Radcliffe wrote about Rickman a couple months after his death. "He is also, one of the loyalest and most supportive people I've ever met in the film industry."

Over two years later, the cast of Harry Potter is ​remembering Rickman to Entertainment Weekly.

Both ​Evanna Lynch, who played Luna Lovegood, and director Chris Columbus remember Rickman for being stoic on the outside, but very sweet on the inside.

"You’re thinking, it’s the guy from Die Hard and going, 'Oh my god.' If he’s in a serious mood, he’s intimidating as hell. But suddenly I had dinner with him ... and when he smiled, he just became the warmest, nicest human being in the world," Columbus said.

"Alan Rickman, pretty much every day of filming, he had a whole troop of little children [visiting]," Lynch remembered. "It was the most bizarre scene to see Snape in this black robe ... surrounded by all these happy little children who were just chatting away to him.”

Oliver Phelps and Warwick Davis recalled Rickman's affinity for iPods.

“I remember once he’d come back from an awards show ... and in the gift box was an iPod, when they’d first come about," Phelps said. "I remember being next to him ... and I ended up showing Alan how to work an iPod, which was not what I thought I’d ever do in my life. He was a very approachable guy once you saw past Snape’s wig."

"I started to wonder, what does Alan Rickman as Professor Snape listen to on his iPod?" Davis stated. "An audiobook? Some Shakespeare? Some classical music? Some techno beats? I don’t know. I never did ask
him, and I wish I had. I’d love to have known.”

​​Rickman's final role was in Alice Through the Looking Glass.
