Crash follows a cast of young doctors as they start work
BBC Wales' new hospital drama TV series, Crash, stars Rhosllanerchrugog actor
Mark Lewis Jones
Mark, 45, who started out treading the boards at acting workshops at Mold Theatr Clwyd while a pupil at Wrexham's Morgan Llwyd, plays A&E consultant Mike Hill in the series created by award winning Tony Jordan, the writer behind programmes such as Hustle and Life on Mars.
The drama follows the lives of four newly qualified doctors in fictional Cardiff City Hospital - but it's actually filmed in an old school in Caerphilly.
In an interview with the Wrexham Chronicle at his parents' home in Rhos, Mark said: "My character can be quite short and brusque but he is confident about his ability as a consultant - he is very sure of himself. He is an imposing figure on the wards and has an air of authority."
Although he has appeared in other hospital dramas, Mark said the latest role has also given an insight into the world of casualty emergency.
"These medical guys came to show us how to do CPR," he said. "We had a scene where we had to resuscitate a patient and it was quite exciting doing 'stand clear' and all that."
There's no rest for Mark. After this series he's filming in France with the role of King Olaf in BBC Wales' fantasy family drama Merlin.
Tony Jordan, whose production company is behind Crash says he's wanted to make a series of this kind for some time, where young characters grow up in a world where their decisions can quite literally mean life or death.
"It's amazing to think of the responsibility these kids have," he says.
"We all trust them with the lives of our children, our parents and our loved ones, yet underneath their scrubs they are still young men and women who are in the process of growing into adults themselves," he adds.
Crash begins on Wednesday 9 September at 8.30pm on BBC One Wales and BBC HD - see it on the
