The team of "Harry Potter", including the lead cast members Danielle Radcliffe and Emma Watson, has paid heart-touching homage to actor Alan Rickman, most famously known for his role of strict professor Severus Snape in the fantasy film series.

Rickman has died following a battle with cancer. He was 69.

Radcliffe played the young braveheart Harry Potter, who for the most part of the series found Snape against him, only to find in the end that he was his well-wisher in disguise. Remembering the brilliance of Rickman on and off screen, in a long post, Radcliffe tweeted, "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."

The 26-year-old star said he liked that the veteran treated him like a colleague not a child on the "Harry Potter" set.
