IT APPEARED to be a case of down(ton) and out for some of the Downton Abbey cast as they celebrated the end of filming the film version of the show a little too hard.

Sophie McShera looked particularly worse for wear as she stumbled through the streets of London with a bleary-eyed Joanne Froggatt barely managing to prop her up.

The actresses looked like the personification of the phrase “partying to the max” as they smiled and slurred their way around town.

The duo joined other members of the Downton cast as they celebrated the completion of filming of the hotly anticipated big screen chapter of the twee ITV drama.

The cast packed out Union Member’s Club on Greek Street in Soho where they knocked back drinks and enjoyed each others’ company until 2AM.

They then stumbled out the door and staggered their way towards Soho house – a short stroll through the streets of Soho.

For 33-year-old Sophie, it looked like a good time had been had – as she needed a helping hand getting out of the first member’s club.

Dressed in a cure denim jumpsuit, the TV star (who plays assistant cook Daisy Mason in Downton) looked like her eyes were glossing over as she floated down a flight of stairs in a pair of shocking pink coloured heels.

Sophie was propped up 38-year-old Joanne – who was looking a little bleary eyed herself.

The actress – who plays Lady Mary’s hand maiden, Anna Bates – appeared giggly and affectionate as she glided through the streets in a rose print dress.

Jo embraced her colleagues as they celebrated the end of filming and a job well done.

Downton Abbey – which is filmed in the UK and features the stunning Highclere Castle near Newbury – is due to jump to the big screen in 2019.

The main cast are due to return to portray life of the fictional aristocratic Crawley family – with Hugh Bonneville returning as Lord Grantham Robert Crawley.

Dame Maggie Smith returns as Violet Crawley, Dowager Countess of Grantham, while Michelle Dockery will reprise her iconic role of Lady Mary Talbot.

The film is a direct sequel to the ITV TV drama that ran for six seasons and over 52 episodes – thrilling millions across the world.

Details of the film’s plot are being kept a close guarded secret – but it will follow events at the end of TV show which concluded at the end of 1925.

A spin-off of sorts is in the works – written by show creator Julian Fellowes – titled The Gilded Age.

Set in the 1880s, the action of this show – due to air in the USA in 2019 – will show life for the upper crust in New York City.

While set before the events of Downton Abbey (which kicked off in 1912), the show is rumoured to feature a younger version of Maggie Smith’s character Violet.
