Marc Elliott has said he's "chuffed" after landing a role in Holby City.
The actor - best known for starring as Albert Square's Syed Masood between 2009 and 2012 - will play new doctor Issac Mayfield, who catches the eye of Dr Dominic Copeland (David Ames).
Marc, 36, said: "I am so pleased to be joining the lovely and incredibly welcoming cast of Holby City, and very much looking forward to playing this complex and flawed character.
"My twin sister was born with the brains and has been working as a fully qualified veterinary surgeon for some years now. I am chuffed that I'm finally going to be able to compete if only in the pretend world!"
Oliver Kent, the BBC soap's executive producer, said: "Charming, confident and twinkly, Issac Mayfield will make a handsome addition to the Keller team and will quickly brighten up Dominic's life."
Marc has already started shooting and will first be seen on our TV screens in June.
