They've just filmed the last ever scenes of Downton Abbey after six series of the hit period drama.

So the cast and crew were certainly in the mood to celebrate as they gathered at a London theatre on Tuesday night to be honoured by BAFTA.

Leading the way was one of the show's leading ladies Michelle Dockery, who looked a world away from her Downton alter-ego Lady Mary in a striking black and white floor-length Valentino number.

Michelle had brought along her mother Lorraine as her date as the Downton gang arrived at the Richmond Theatre in south west London.

Joining the 33-year-old on the red carpet was her on-screen sister Laura Carmichael (Lady Edith), who looked summery in a floral maxi dress by Erdem with her hair tied back in a loose updo.

Also going for white was Joanne Froggatt (Anna Bates), who looked stunning in a white floor-length Victoria Beckham gown with bejewelled straps across her back.

Fellow 'below stairs' Downton employees Sophie McShera (Daisy Mason) and Phyllis Logan (Mrs Hughes) looked a world away from their characters in two glamorous numbers.

Wearing one of the more daring necklines on the predominantly demure red carpet was Zoe Boyle, who showed some skin in a low-cut floral gown.

She famously played Lavinia Swire, who was briefly engaged to Matthew Crawley in Series 2 before dying of Spanish flu - paving the way for his eventual marriage to Lady Mary.

The event will see the cast and crew accept a Special Award from the British Academy of Film and Television Arts for the show's phenomenal success both in the UK and internationally.

Jonathan Ross is hosting the event, which is being filmed for BAFTA Celebrates Downton Abbey, which will be broadcast on ITV later this year.

Gareth Neame, executive producer of the show and Managing Director of Carnival Films, said of the BAFTA honour: '‎As Downton Abbey moves towards its conclusion with the final season this autumn, I speak for the entire cast and crew when I say how honoured we are that the Academy will recognise the show with this Special Award.

'Not only is Downton a much-loved show in Britain, it has had huge success in both the US and right around the world, waving the flag for Britain and our creative content and that's why the BAFTA recognition means so much to us all.'

The final series of Downton Abbey is set to hit British screens in September, with the final episode being broadcast at Christmas.

It was revealed over the weekend that the final series will see the Crawley family having to downsize as their extravagant lifestyle doesn't become financially viable in the changing world.

Hugh Bonneville revealed the final series, which is set in 1925, has 'a flavour of the end of an era'.
