People still can’t get enough of Kristin Scott Thomas and Gary Oldman in “Slow Horses.”

“We’ve worked together before. We’ve got very good acting chemistry. And it’s really fun. These two characters are so brilliantly written. You can’t beat great writing,” she tells Variety at the Monte-Carlo Television Festival, where she picked up the Crystal Nymph Award for her career.

The show also has some fans in high places.

“Apparently, all the MI6 and MI5, they love it. They really love watching it! We’ve never seen people like this. We’ve never seen the inside of these spy places.”

Her character, Diana Taverner, is “the ultimate ice queen,” she says.
