Rickman, who played Hogwarts teacher Severus Snape in all the Potter films, lost his battle with cancer on Thursday (14Jan16) and there has been an outpouring of tributes from his famous fans, friends and colleagues.

Daniel Radcliffe, Emma Watson and Harry Potter creator J.K. Rowling were among the first celebrities to salute the late star, and Emma Thompson, Matthew Lewis and Rupert Grint also issued statements.

Now their castmates have flooded social media to honour Rickman with tributes, too.

Bonnie Wright, who played Ginny Weasley in the Potter films, told JustJared.com, "As a young actor I was incredibly fortunate to have worked with Alan and be exposed to his graceful methods. He had that rare ability to shift the energy of a set the moment he walked on. I will never forget his deep, measured and theatrical voice. He will be missed by the Potter family."

Bower added, "Devastated to hear about the passing of Alan Rickman. I had the pleasure of working with him on my first movie. A true legend and gentleman."

Meanwhile, Isaacs tweeted, "The polar opposite of the icy, manipulating characters he became best known for, Alan was hilarious, warm-hearted and fabulous company. To witness his laser-like honesty and precision as an actor in the flesh was a rare privilege. A great artist and a lovely man."

And Davis added, "So terribly sad to hear of the passing of Alan Rickman. Honoured to have shared the screen with him... He'll be sorely missed."
