British actor Alan Rickman, who died Thursday at 69, was beloved in the industry for his roles as Severus Snape in the Harry Potter movies as well as roles in “Die Hard,” “Truly Madly Deeply” and “Love Actually.” Among those remembering the versatile actor, known for his delicious villains, were Harry Potter himself, Daniel Radcliffe, and Potter creator J.K. Rowling.

Radcliffe wrote on his Google Plus page “Alan Rickman is undoubtedly one of the greatest actors I will ever work with. He is also, 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. I know other people who’ve been friends with him for much much longer than I have and they all say “if you call Alan, it doesn’t matter where in the world he is or how busy he is with what he’s doing, he’ll get back to you within a day”.

People create perceptions of actors based on the parts they played so it might surprise some people to learn that contrary to some of the sterner (or downright scary) characters he played, Alan was extremely kind, generous, self-deprecating and funny. And certain things obviously became even funnier when delivered in his unmistakable double-bass.

As an actor he was one of the first of the adults on Potter to treat me like a peer rather than a child. Working with him at such a formative age was incredibly important and I will carry the lessons he taught me for the rest of my life and career. Film sets and theatre stages are all far poorer for the loss of this great actor and man.”

“Harry Potter” author J.K. Rowling tweeted her condolences to his family, saying “We have all lost a great talent.”

“Harry Potter” co-star Emma Watson remembered Rickman on her Facebook page, saying, “I’m very sad to hear about Alan today. I feel so lucky to have worked and spent time with such a special man and actor. I’ll really miss our conversations. RIP Alan. We love you.”

Emily Hampshire, who worked with Rickman on “Snow Cake,” said, “Alan was not only a great actor but a loyal, generous and devoted friend. We met in 2005 and he remained a friend and mentor till the end. I never understood why he was so good to me  — he’d come to my movie premieres, invite me to his, call regularly just to check in/chat!??… but i ultimately realized that that is just who Alan was.”

Fellow British actor Stephen Fry remembered Rickman as a “stunning stage and screen presence.”

Director Edgar Wright said he “made screen villainy a true art form.”
