Doctor Foster hauled in more than 10 million viewers for its series finale, a feat rarely achieved in a world of multi-channels.
But the tale of a woman betrayed by her husband and seeking revenge captured the audience’s imagination thanks to its original take on a well-worn plot and pitch-perfect performances.
“It has a fantastical, weird sexy edge as well as being deep-rooted in naturalism. It also has an exaggerated way of showing how far you could go if you really wanted to,” says Suranne Jones, who returns to the title role alongside Bertie Carvel as her estranged husband Simon and Tom Taylor as their son, Tom.
After Gemma Foster dramatically exposed her husband’s betrayals, he left town but at the beginning of series two, Gemma’s life is destabilised when he, Kate (the woman he left her for, played by Jodie Comer) and their child return.
If you thought series one was tense, prepare yourselves as these next five episodes are set to get even darker. But while Simon became one of the nation’s most disliked characters, Jones feels Gemma is equally flawed.
“They can both be unlikable people and what betrayal does to a person can make them ugly,” she says.
