British actor Paul Ritter, whose credits include Harry Potter and James Bond movies, has died of a brain tumor, his agent said Tuesday.

He was 54.

“It is with great sadness we can confirm that Paul Ritter passed away last night,” his agent told The Guardian.

“He died peacefully at home with his wife Polly and sons Frank and Noah by his side,” the agent said, confirming he had “been suffering from a brain tumor.”

Ritter was initially known as a stage actor, and was nominated for an Olivier award in 2006 for “Coram Boy” and a Tony for his 2009 starring role in “The Norman Conquests,” The Guardian said.

He also appeared in a number of high-profile movies, playing Eldred Worple in “Harry Potter and the Half-Blood Prince” and government adviser Guy Haines in the 007 movie “Quantum of Solace.”

In his native Britain, the Kent-born actor was best known for the Channel 4 TV show “Friday Night Dinner.”

“Paul was an exceptionally talented actor playing an enormous variety of roles on stage and screen with extraordinary skill,” his agent told the UK paper.

“He was fiercely intelligent, kind and very funny. We will miss him greatly.”
