Complete cast breakdown of Netflix's Hostage: Who plays whom and where you've seen them before? 

Hostage is a British political thriller miniseries created by Matt Charman that began streaming on Netflix on August 21, 2025. The narrative revolves around a summit between the leaders of the UK and France, which takes a dreadful turn. The husband of the British Prime Minister is kidnapped, and the visiting French president is blackmailed, leading them to face unimaginable choices. Forced into a rivalry with their careers and lives in the balance, they race against time to take the lid off the nefarious plot. 

In an interview with Netflix’s Tudum, series star and executive producer Suranne Jones stated: 

“I’m thrilled to be on Netflix, in something I’m really proud of. It’s been something I’ve wanted to do for a long time. We’d talked about projects previously, but for me, it was about finding the right thing. Hostage was perfect — me and Matt together, backed up by this brilliant, supportive team. I loved it.” 

Her enthusiasm has been echoed by the creator, who added:

“I’ve been dying to find the right story to tell with Suranne and I honestly believe what she’s done with this character is going to blow the Netflix audience away. An embattled British PM in the middle of a fight for her country and her family — she’s fierce, ruthless, and you can’t take your eyes off of her.”

The series comprises five episodes in all, with a runtime of approximately 42 minutes each. It has been well received by critics, earning a rating of 85% on the film and television rating website Rotten Tomatoes.
