Dust off your evening gowns because the rumours are true - Downton Abbey is coming to the big screen.

Focus Features has announced the British television show, which began its six-season run in 2010, will be made into a film and will begin shooting by the end of the year, according to Entertainment Weekly.

Downton Abbey aired on ITV in the UK and PBS in the US, receiving critical acclaim and winning 15 Emmys. It is the most nominated non-American show in the history of the prestigious awards.

The lavish period drama's main cast will reportedly return, with Entertainment Weekly reporting leads Michelle Dockery, Hugh Bonneville, Maggie Smith and Joanne Froggatt have signed on.

While plot details are scant, The Guardian reports the film will pick up just after the final season's finale, which was set in 1926.

Julian Fellows, the Oscar-winning writer who created the show, will write the film's screenplay, while The Book Thief director Brian Percival will take the helm.

In a press statement, producer Gareth Naeme said, "When the television series drew to a close, it was our dream to bring the millions of global fans a movie, and now, after getting many stars aligned, we are shortly to go into production."

Universal Pictures and Focus Features will distribute the film across the globe.

A New Zealand release date has yet to be set.
