Celebrating its 35th anniversary this year audiences will see new characters and be reunited with some old faces.

Osi Okerafor (Death in Paradise, King Gary) joins as Matthew, a locum registrar with a history of practicing medicine in the world’s trouble spots and a deep and enduring love for old flame Fenisha. How will Ethan respond to Matthew joining the team? Is there still a spark between Fenisha and Matthew? And how will all three cope with working together in a tight-knit emergency team?

Osi’s casting was announced alongside Elinor Lawless who will be joining Casualty as new consultant Stevie, later this year.

Osi Okerafor says: “It’s a pleasure to become a part of the Casualty team. Everyone here is so genuinely friendly and it’s a very exciting environment to work in. I’m excited for viewers to see Matthew’s love for his patients and his willingness to do whatever it takes to care for them; it’s a quality I really admire in him.”

Loretta Preece, Series Producer of Casualty, says: “I am delighted that Osi and Elinor will be joining the Casualty family. As an actor, Osi has it all; he’s handsome and debonair, sensitive and steadfast, passionate and unpredictable. Osi has been delightful to work with and he and Olivia have a very special on-screen bond. With Osi’s beautifully layered performance we slowly reveal some deep undercurrents – he is far more than a classic romantic leading man. Eli is an exceptional actress and a force of nature. With Stevie, Eli brings new and dangerous energy into our world – she’s charismatic, contemporary, compelling and on occasion very unsettling. Her wonderful character and additive backstory is an exciting part of defining a new and exciting era for Casualty as we go into our 35th year.”

Osi will appear on screen as Matthew later this month. More details about the 35th anniversary will be announced in due course.
