BBC’s Casualty has a new doctor ready to hit screens and join Holby City’s emergency department.

Call The Midwife star, Olly Rix, 39, is set to join the cast of the popular BBC show as Flynn Byron – the new Clinical Lead Consultant.

His character, described as ‘charming but complicated’, will make his debut appearance in March in the medical drama’s upcoming miniseries Internal Affairs.

Flynn has only just completed a tour of duty with the military and has to grapple with trauma from his past while trying to make a difference in his new role.

Olly previously played Matthew Aylward in BBC series Call The Midwife who left to go to New York.

His character married Nurse Trixie Franklin, played by Helen George, in season 12 of the drama.

Speaking of his new role, Olly described his excitement for viewers to meet the new addition.

He said: ‘It’s been a pleasure to join the Casualty cast in such a dynamic role. Flynn crashes into the world of it from a very different background, resulting in a complex and exciting story in Internal Affairs and beyond.

‘It’s a brilliant new chapter for the show and I am excited for the audience to get to know Flynn.’

Roxanne Harvey, Executive Producer of Casualty for BBC Studios, shared that Flynn’s character would ‘resonate’ with fans.

He said: ‘Flynn’s journey promises to resonate with viewers, exploring the often emotional toll of working in the NHS, the cost of making tough decisions, and the possibility of redemption when you’re confronted with the consequences of your actions.’

The miniseries will also feature Downton Abbey actor Robert Bathurst, in a guest role as surgeon Russell Whitelaw.

The most recent series – Public Property – has seen plenty of drama in the hospital. 

One episode last month, called On Trial, saw a tragic death bring Dylan Keogh, played by William Beck and Jodie Whyte, portrayed by Anna Chell, together.

While Rash Masum, played by Neet Mohan attempted to hide a secret from Tariq Hussein – Manpreet Bachu.

Another episode, Bite The Bullet, saw even more dramatic turns with trainee paramedic Indie Jankowski (Naomi Wakszlak) lying about passing a vital university module.

As well as heightened tensions between Luka Malinovsky (Tom Mulheron) and mother Faith Cadogan (Kirsty Mitchell).

Casualty airs on BBC One and is available to stream on BBC iPlayer.
