The Bafta winner and her co-star Julie Delpy are opening up about the Netflix thriller that's got everyone talking.

Matt Charman follows 'Treason' with another five-part London-set show, this one tracking a high-stakes summit between the British prime minister and the French president.

In Hostage, Suranne portrays British Prime Minister Abigail Dalton, who is left with an agonising dilemma when her spouse Dr Alex Anderson (portrayed by Ashley Thomas) is abducted and his kidnappers demand she step down from office.
