Downton Abbey star Laura Carmichael has said that talks are still under way for a big-screen version of the hit period drama.
The show's executive producer, Gareth Neame, hinted earlier this year at the prospect of a feature film about the Crawley family and their servants, to follow the sixth and final series.
Now Carmichael, who plays Downton's Lady Edith, has told ITV show Lorraine that she is holding out hope for a film but has not yet seen any sign of a movie script from creator Julian Fellowes.
"They're talking about it. It's mad," she said of the possibility of Downton being adapted for the big screen.
"But we're still in the midst of filming the last series. We'll see if Julian writes it."
Carmichael is preparing to wave goodbye to the series after five years of success around the globe.
She said she would miss her co-stars, who she called "the gang" and "like family" as well as "the clothes and dressing up" for her role.
Despite becoming such a big hit for ITV, Carmichael said she could still live her life anonymously because she looks nothing like her alter-ego Lady Edith, who is seen as the "plain" sister in the family.
"I look quite different. It's nice because I get to have a pretty normal time of it," she said.
Carmichael was working as a receptionist at a doctor's surgery when she was invited to audition for the drama.
She said being on the show, which also stars Maggie Smith and Hugh Bonneville and launched the careers of Michelle Dockery, Lily James and Dan Stevens, was like "an acting masterclass".
"Working with all those actors has been like going to school. That's the most amazing thing," she said.
Executive producer Neame said earlier this year he was "very interested" in making a Downton movie.
"It's definitely something we're contemplating. It would be great fun to do. I think it would be a wonderful extension of everything people love about the TV show," he said.
"But I can't confirm that it's going to happen. It would take a lot of planning and thinking about. We shall see."
