The new spy thriller Black Doves stars two of Britain's biggest actors, who had surprisingly never even met before working on the project together.
Ben Whishaw stars opposite Keira Knightley in the six-episode Netflix series and he tells 9honey Celebrity that despite being strangers when they booked the job, they just happened to "click" straight away.
"We didn't know each other at all," Whishaw says on the red carpet at the TV show's London premiere.

"We didn't even really do much rehearsing or much talking, but something just, we just clicked. We just got on immediately well and liked and trusted each other."
The actor, who is also known to fans as the voice of Paddington Bear, said "it was such a pleasure" working opposite the Atonement star.

Whishaw and Knightley play spies Sam Young and Helen Webb who work together to solve a murder mystery.

Director Alex Gabassi tells 9honey Celebrity they both wanted Whishaw on the show, saying there was "no one else" they wanted to play Sam.

"It's the quintessentially British combination – I knew that Keira and Ben, because of the way Joe [Barton] writes, there is a musicality to that kind of dialogue that you needed a delivery that was very clear, with some irony there.
"And Keira can do that, Ben can do that. So we put them together, I mean, it's just, it's a dream. So for me, it really worked really well [but] I always knew it would work."

"It's was crazy ... I remember the read through and seeing them all together for the first time and looking around this table and just having Sarah Lancashire and Keira Knightley and Ben Whishaw and Andy Buchan and Kathryn Hunter, all these amazing people," Barton tells 9honey Celebrity.
"Honestly, I've been really lucky to work with some incredible actors in my career but just the pure quantity of talent was like, yeah, mad."

That combination is also what attracted Sarah Lancashire to the role of Reed - boss to Whishaw and Knightley's characters.
"It was tremendous – all my work is opposite either Keira or Ben or both of them together," Lancashire tells 9honey Celebrity.
"So I was very lucky, kind of spoilt."

"It feels full circle, because this is, 100 metres away from here, there was a bench where everything starts, that's where the story is triggered," Gabassi says of the series.
"So for me, it's really special to be here."
"I wanted to escape the usual glassy, cool, cold London, I wanted to go colour, texture, visceral and that's what we did, I hope."
Black Doves drops on Netflix on December 5.
