Meanwhile the official Downton Abbey account also posted the actress’ snap and confirmed that filming began yesterday – exciting!

This news went down well with fans of the show who were thrilled to get a glimpse of the highly-anticipated film.

“I can’t wait to see it!!!! Lots of love to the entire cast!!!!” one follower commented, whilst another wrote: “SOOOOO EXCITED!!”

Meanwhile one added: “why is today only the first day of filming! I’ve been going through Downton withdraws for 2 years! I need to see this movie already”

It comes after it was announced back in July that the hugely popular ITV series would be returning as a movie following months of speculation.

Many original cast members are set to star in the big-screen adaptation including Maggie Smith, Laura Carmichael, Hugh Bonneville and Elizabeth McGovern.

There will also be some new faces including Imelda Staunton and Stephen Campbell Moore.

The cast already seem to have been enjoying being reunited, with Hugh joining Allen Leech – who plays Tom Branson – to watch Elizabeth in a play this week whilst filming got underway without them.

Downton Abbey creator Julian Fellowes has written the screenplay for the movie and it will be directed by Brian Percival.

The programme came to an end in 2015 after six series charting the lives of the Crawley family and their staff.

It won many awards including three Golden Globes and proved popular with audiences across the world.
