The actor will appear on screen in the BBC One show in May, taking on the part of salesman Tommy Sandison.
Doctors producer Natasha Carlish told Digital Spy today (February 13): "We are thrilled that Roy Hudd is returning to Doctors for a very special episode in which he plays Tommy Sandison, the husband of a woman with dementia.
"In the episode, Roy will play a salesman who has to make the most important sale of his life, and so find a way to help the woman he loves more than life itself. It is a perfect role for Roy, who brings warmth, compassion and an inherent charm to any character he takes on.
"I have always greatly admired his work and I very much look forward to welcoming him back to the world of Letherbridge."
The 76-year-old has previously had other guest roles in Doctors, mostly recently in 2011. His varied screen credits include his appearances on Coronation Street as undertaker Archie Shuttleworth.
Hudd's latest scenes will air on Tuesday, May 7 on BBC One.
