The actress will be joining the cast of the long running medical drama this autumn.
Jo will be playing Max McGerry, a consultant neurosurgeon who initially comes to Holby to visit a patient.
“I am thrilled to be joining such an amazing show, which I have been a fan of for years. Playing Max will be a pleasure; she is very complex with no filter.” – Jo Martin
The beeb further note that her character has a sterling reputation that doesn’t go unnoticed by Ric, who asks her to hang around for a very important reason, but one that comes with a lot of risk.
Viewers can expect to see the show “explore highly topical questions about the future of the NHS” through the character, while Max’s personal life will also become “increasingly turbulent”.
“Jo is a fabulous addition to the Holby gang, both a hugely talented dramatic actor and comedian. She’s been on our admiring radar for some time while we thought up the right part for her. Max is a brilliant, multi-faceted character [who has] no patience whatsoever for political correctness, or ‘snowflakes’ as she calls them.” – Simon Harper, Executive Producer
Jo has begun filming Holby City with her debut in the show to be screened this autumn. Jo’s previous credits include Back To Life, Fleabag, The Long Song and Silent Witness.
