Doctor Who and Harry Potter star Simon Fisher-Becker has died at the age of 63, his agent has confirmed.

Kim Barry of Jaffrey Management issued a statement paying tribute to the star. “Today I lost not only a client in Simon Fisher-Becker, but a close personal friend of 15 years standing. I shall never forget the phone call I made to him when he was offered the part of Dorium Moldovar in BBC’s Doctor Who.

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

His husband also shared the sad news on Simon’s Facebook page. “Hello everyone. This is Tony, Simon’s husband.

“I have some very sad news. At 2:50 this afternoon Simon passed away. I’ll be keeping this account open for a while. I’m not sure at this point if I’ll be posting again. Thank you,” he wrote.

Simon’s cause of death has not yet been revealed. He became a sci-fi icon when he was cast as black marketeer Dorium Maldovar in Doctor Who. He was also beloved for his portrayal of ghost The Fat Friar in Harry Potter and the Philosopher’s Stone in 2001.
