The 39-year-old actress has won rave reviews for her portrayal of GP Gemma Foster in the two series of the BBC One drama, and creator Mike Bartlett has spilled that he has a story mapped out for another run, which will focus on the doctor's missing son Tom Foster.

Suranne is very proud of her work on the programme but is unsure if she can commit to another six episodes because she already has acting commitments she has agreed to.

She will next be seen on TV in Lennie James' missing child drama 'Save Me' for Sky Atlantic, with plans for a second series already underway, is appearing in theatre play 'Frozen' and is due to start shooting Sally Wainwright's 'Gentleman Jack'.

Discussing Mike's plans for 'Doctor Foster' on 'This Morning' on Monday (26.02.18), Suranne said: "I don't know. With 'Save Me' also, there's room for more, Lennie has been saying he'd like to make a second one. Then I'm doing 'Gentleman Jack' after finishing 'Frozen' so I don't know."

Questioning whether Tom [Tom Taylor] should even be reunited with his dysfunctional and damaging parents Gemma and Simon Foster [Bertie Carvel] with hosts Phillip Schofield and Holly Willoughby, she added: "Would you really want him coming back to these damaged parents. After the programme we'll finish the wine over there and we'll work out the story and let Mike know."

Suranne had intended to take a break from acting after making 'Doctor Foster' but once she was sent the script for 'Save Me' her husband Laurence Akers knew immediately she wasn't going to say no to the job offer.

Suranne and Laurence have a young son together and she admits she's has to make an effort to do things with her little boy because she's out of the home so much due to her long hours on London's West End.

She shared: "I'd finished 'Doctor Foster' two and I planned a trip to LA and then I was gonna have a break but then this script came up and Lennie got in touch with me ... First of all my husband rolls his eyes and then he goes, 'You're doing it aren't you?' I'm in the theatre at the moment in Frozen, the West end keeps me away from the home. I get in really late from the West End. I get up really early now and I'm like a super-needy mum and I'm like, 'Let's have breakfast and play games.' "
