Casualty star Olly Rix has opened up about the difference in working on the long running BBC medical drama compared to his previous show Call The Midwife. Olly, 40, recently joined Holby ED as clinical lead Flynn Byron – however he was very much on the other side of the medicine during his time in Call The Midwife as businessman Mathew Aylward, who he played for three years.

Speaking exclusively to Express.co.uk the actor said: “I mean Casualty especially, there’s a lot going on. It’s not just the babies coming out sideways or whatever. It’s, it’s intense, medically, very, very involved. So I don’t think they’re remotely comparable. I mean, Casualty is a whole different ball game and I have a lot of respect for all the other actors doing it,” he said. Acknowledging the show is a team effort he added: “We also should shout out the medical professionals that we have on the floor.

“There’s normally at least four or five at any given moment. So there are a lot of brilliant medical professionals helping us, hopefully making it look like we know what we’re doing.”

Despite this Olly confessed to occasionally struggling with the medical jargon required of the role.

“I mean, that’s the joy of TV, right? You get to go again,” he laughed.

“Sometimes you just get a certain medical procedure or bit of equipment or something that you just can’t get your head around.

“No matter how many times you practice saying it at home you just know, first take, it’s going to go wrong and it does.

“And then you, then you adjust, and you get on with it,” he said.

“I mean, it’s fun. It’s a new challenge. It doesn’t let up. It doesn’t get easier,” he confessed.
