British actor Alan Rickman, a veteran of dozens of films, has died at age 69. Recently, Rickman was most well-known for portraying the complicated villain Severus Snape in the films based on J.K. Rowling's Harry Potter books.

"Rickman had been suffering from cancer," The Guardian reports.

Rickman appeared in an array of blockbuster films during his prolific career, from 1988's Die Hard with Bruce Willis to 2003's Love Actually and the Harry Potter films.

There are no words to express how shocked and devastated I am to hear of Alan Rickman's death," author J.K. Rowling said via Twitter today. "He was a magnificent actor & a wonderful man."

Blessed with a rich and deep voice, Rickman brought intelligence and humanity to a wide spectrum of roles, judiciously deploying what seemed to be a bottomless supply of frowns and smirks that endeared him to his fans.

While his voice became something of a trademark, Rickman once said that he endured much criticism for it in drama school. One voice teacher, as he recalled in 2007, told Rickman that he sounded as if his voice was "coming out of the back end of a drain pipe."

Explaining his own opinion of his voice, Rickman said, "Well, it's what I'm stuck with, so it's not like I can go and get another one. And also, I don't hear what anybody else hears. So it's always a bit of a shock, you know. And it never goes away."

While he might be famous for playing villains, Rickman once told NPR that those roles are "a very small part of whatever I've done. It's like two or three parts, and they just happened to have big publicity budgets."

Rickman also directed films and theatrical works, and he acted in plays from Shakespeare's Antony and Cleopatra to Noel Coward's Private Lives.

A former member of the Royal Shakespeare Company, Rickman spoke to NPR in 2011 about his stage work in the U.S.:

"I love working in New York theater. ... It is very demanding, but it's good to be in a city where you feel that theater is actually part of the life of the city. You know, London is so sprawling, and you can sometimes forget that anybody else is on a stage anywhere else. But here, it's, you know, your friends and neighbors."

Three films from the 1990s help describe Rickman's range.

In 1991, he turned in a memorable performance as the Sheriff of Nottingham in Robin Hood: Prince of Thieves -- a film whose legacy these days isn't helped by Kevin Costner's hair, but which was the second-most popular film in theaters that year.

In 1995, he appeared in the director Ang Lee's Sense and Sensibility, playing Colonel Brandon opposite Kate Winslet's Marianne Dashwood.
