Keira Knightley wows in Matrix-inspired black PVC coat and dress as she leads the arrivals for her spy thriller Black Doves premiere at the BFI

Keira Knightley looked incredible in a Matrix-inspired look as she walked the red carpet for her new spy drama on Tuesday evening.  

Appearing at the BFI on London’s Southbank, Keira, 39, wore a Chanel Couture leather long buttoned coat with a sheer lace skirt.

Thought to cost around £40,000, the Pirates of the Caribbean actress paired the outfit with waved hair, heavy eyeliner and a pair of small heels – despite last month admitting she can no longer walk in them.

Happy Valley’s Sarah Lancashire, 60, also walked the carpet in a long brown coat and heeled boots as she showed off her new bob hairstyle.

The new series will mark Sarah's return to television.

The actress won critical acclaim for her role as Catherine Cawood in the BBC's Happy Valley, starring alongside James Norton as murderer Tommy Lee Royce.

She also scooped the Leading Actress Award at the BAFTA TV Awards in May and the Memorable Moment Award also went to Happy Valley.

Also on the red carpet was Andrew Buchan, 45, and Ben Whishaw, 44, who also star in the new series.

Keira plays a spy and mother who is spilling her politicians secrets until it appears her cover has been blown.

The premiere for the new spy drama comes after Keira opened up about how the 'double faces' of juggling work and motherhood helped her prepare for her new spy role.

Speaking to the Radio Times this week, Keira - who shares young daughters Edie and Delilah with husband James Righton - revealed how her real life as a wife and mother helped inform the role.

She said: 'In life it’s those double faces that you have.

'Then suddenly you’re at work and you’ve got your work face on and then you’ve got your kid on the phone and you’re, "Oh baby, are you OK?"

'So it’s that thing I think we all know and that we all do, but ramped up to ten, or 11 or 12. And that’s what I liked. It made me giggle.'

'We all do it. For me, I’m on a film set and then it’s, "Oh, you passed your spelling test – I love you so much!"

'Whereas this is, "Darling, I love you so much and they’re just about to kill me. Kiss darling, goodbye".'

In the new Netflix series Keira is a spy for the Black Doves organisation, headed up by Sarah Lancashire’s character and has been giving them political information for ten years from her husband, played by Andrew Buchan.

Her position is them compromised and she is attacked by assassins only to be saved by a friend from her past, Sam Young, played by Ben Whishaw.

Last month speaking to The Times, Keira said she couldn’t believe how she used to dress as she reflected on her noughties fashion.

'It was all about my midriff,’ the actress said.

'I don't have the midriff any more, so it's not coming out.’

Speaking about always wearing Dr Marten boots she said: ‘I've got a brown pair and a black pair, and it's very hard to ever take them off. I've no idea how to walk in heels any more.'

Netflix released its first trailer for Black Doves - which sees Keira and Sarah Lancashire take on leading roles as spy and spymaster - last month.

It gives fans their first taste of the new thriller, which follows Keira's character Helen as an agent passing on secrets of her politician husband [Andrew Buchan].

Keira is a spy for the Black Doves organisation, headed up by the enigmatic Reed [Sarah], and has been giving them political information for 10 years.

Helen's secret lover Jason [Andrew Koji] is assassinated and Reed informs her that her position in the organisation may have been compromised.

Her theory is proved right when Keira is attacked by assailants, only to be saved by a friend from her past, Sam Young, played by Ben Whishaw.

Sam is a suave, Champagne-drinking assassin but has been out of the game since a failed job with disastrous consequences.

As his past threatens to catch up with him, his task is to protect Helen as she investigates who killed Jason and why.

Helen then makes Sam promise to keep her alive and keep her family safe, so she has time to find out who killed Jason and take her revenge on them.

Netflix fans already 'can't wait' the must-watch spy thriller which arrives to screens on December 5 with six episodes, set against the backdrop of London at Christmas.

Helen and Sam set off on a mission that will lead them to uncover a vast, interconnected conspiracy.

One that links the murky underworld of London to a looming geopolitical crisis – and leads them to question the cost of the moral choices they've made.

The Netflix series is written by Joe Barton and Keira is listed as an executive producer.

Earlier this month, Netflix shared a first look clip at the talented cast as they have 'never been seen before'.

In the short video, Sarah Lancashire's character says: 'I'm looking to hire someone. No one knows if they can really do it until they try and then they find out pretty quick. Are you sure this is what you want?'

Elsewhere in the dramatic teaser, Keira and Ben's characters appear on screen with blood splattered across their faces.
