Simon Fisher-Becker, 'Harry Potter' actor, dead at 63

"Today, I lost not only a client, Simon Fisher-Becker, but a close personal friend of 15 years standing," Kim Barry of Jaffrey Management told Fox News Digital. "I shall never forget the phone call I made to him when he was offered the part of 'Dorium' in Dr Who. He had been a fan of the show since he was a child."

"Simon was also a writer, a raconteur and a great public speaker," she added. "He helped me out enormously and was always kind, gracious and interested in everyone. My condolences go to his husband Tony, his brother, nieces and nephews and his legion of fans."

Fisher-Becker's husband revealed the news on Sunday via the actor's Facebook page.

"I'll be keeping this account open for a while," he added. "I'm not sure at this point if I'll be posting again. Thank you."

The Fat Friar ghost from the 2001 film is Hufflepuff House's resident specter.

Fisher-Becker returned as Dorium in "Doctor Who: The Eleventh Doctor Chronicles and Jenny - The Doctor's Daughter" and the "Doctor Who" fan-film "Tale of a Timelord."

He boasted over 50 acting credits throughout his career, including "Les Misérables," "Waterside" and "Puppy Love."
