British actor Alan Rickman passed away at the age of 69, after a lengthy battle with cancer. He was, of course, Severus Snape.
Rickman was a brilliant player of villains, although he also played the romantic lead in Truly, Madly, Deepy and Love, Actually.
He was also a stage actor and did a stint with the Royal Shakespeare Company - which definitely shows in his style.
In a long career, he was, amongst other less genre credentials, Severus Snape. He voiced Marvin in The Hitchhiker's Guide to the Galaxy. He was, of course, Alexander Dane in the Star Trek spoof Galaxy Quest. He was Metatron in Dogma, the Sheriff in Robin Hood: Prince of Thieves, Hans Gruber in Die Hard.
His last work was voicing the Blue Caterpillar in Alice Through The Looking Glass, with a release date this year.
He will be missed.
