Suranne Jones has revealed she visited a real GP’s surgery to prepare for playing one in new BBC drama Doctor Foster.

The star of Coronation Street and Scott and Bailey plays Gemma Foster in the new series, a GP whose seemingly perfect life is thrown into disarray when she suspects her husband of an affair.

Suranne revealed to research the role she visited a GP surgery and “sat in a corner like some mad actress writing stuff down, as people were opening up and having blood tests and doing pee samples”.

“I felt very awkward, but privileged to be in there as well,” she confessed.

The 37-year-old actress also watched the fly-on-the-wall Channel 5 series, GPs: Behind Closed Doors.

“My husband would come in and I’d be crying at all these real people in intimate situations,” she revealed.

Suranne admitted she found being the star of the drama very demanding, but the toll it took on her actually helped her performance.

She explained: “I think in the whole five hours, there are about four scenes I’m not in.

“Filming-wise, it’s been like The Truman Show. I’ve never done anything like that before. The big projects I’ve done have always been shared.”

“The more extreme she got, the more exhausted I was getting,” she added.

“According to the execs, that actually worked really well. I think they were basically saying I looked really tired and terrible, which was great!”

Doctor Foster begins on BBC One on Wednesday, September 9
