Severus Snape actor Alan Rickman already had a career spanning more than 20 years by the time he took he took on the menacing role of Snape in "The Sorcerer's Stone." By then, he'd already had starring roles in major Hollywood movies such as "Die Hard," and had worked with some of the industry's biggest names including Bruce Willis, Kevin Costner, and Liam Neeson.

However, one of the young "Potter" actors – Matthew Lewis – managed to pluck up the courage to approach Rickman on the last day of filming the mammoth franchise. Lewis, who played Neville Longbottom, then ended up in Rickman's trailer, where the British veteran gave him a cup of tea and some career advice.

Lewis recalled the touching story during a recent appearance on Inside of You with Michael Rosenbaum.

"I went to his trailer and I just said to him, 'Hey, I know it's your last day, and I just wanted to say this has been incredible, to have worked with you for so long,'" Lewis recalled.

Lewis said that he told Rickman that he had always been "terrified" of him, but that he'd really appreciated the time they had working together despite not speaking very much. Rickman, Lewis said, was "incredible."

"I just want to say thank you for allowing me to work with you for 10 years and not ever shouting at me or treating any of us as anything less than your equal.'"

Lewis continued: "He was like, 'Come on in.' And he put the kettle on, and we had a cup of tea and we chatted about what I was going to do in my career moving forward and what he recommended I do."

Rickman, who died in 2016 aged 69 from cancer, left a great impression on many of his younger costars in the "Potter" series.

Harry Potter himself, Daniel Radcliffe, left a touching tribute to Rickman on Facebook shortly after the actor's death. According to The Independent, Radcliffe wrote that Rickman was "one of the loyalest and most supportive people I've ever met in the film industry."

"He was so encouraging of me both on set and in the years post-Potter. I'm pretty sure he came and saw everything I ever did on stage both in London and New York. He didn't have to do that," Radcliffe wrote.

Rickman starred in all eight "Potter" movies, and people loved his performance as Snape so much that there was even a campaign to get Rickman nominated for the best supporting actor Oscar for the final "Potter" movie, "Deathly Hallows Part 2."

Radcliffe himself said at the time: "I don't think there is going to be another performance from an actor in a supporting role that is so powerful."

While that campaign never materialized, Rickman did win a BAFTA award for best supporting actor for his playful turn as the Sheriff of Nottingham in 1991's "Robin Hood: Prince of Thieves." Rickman also starred in "Love Actually," "Sweeney Todd: The Demon Barber of Fleet Street," and "The Hitchhiker's Guide to the Galaxy."
