Actor Stevens lives in the past

‘Downton Abbey’ star is making a film set in 1913 England and based on a true story.

LONDON — “Downton Abbey” star Dan Stevens has been spending twice as much time in the past.

Along with shooting the third season of the 1920s-set Golden Globe- and Emmywinning TV show, he’s been filming and executive producing another period project in London, playing one side of an Edwardian love triangle in the movie “Summer in February.”

The tight schedule means Stevens is the earnest Matthew Crawley amid the upper crust of Downton Abbey one day — then a 1913 land agent who finds himself in a community of unconventional artists the next.

“It’s been a bit of a headache, but fortunately they’re not too far apart in terms of period, which is one good thing,” Stevens said on the set of his new film in Twickenham, outside London.

Jumping between two sets is not something he’d do again, but “Summer in February” is a passion project for the 29-year-old.

The film is based on a book by Jonathan Smith, a teacher from his old school who also adapted the screenplay. They had talked about the project since the actor was a teen.

“The book came out around the time that I met him and he always joked that if it got made into a film or TV show, that I’d make a good Gilbert,” he said.

Based on a true story, the film features Stevens as Gilbert Evans, a land agent for the Lamorna Valley estate, which has become home to a group of artists.

Australian actress Emily Browning plays the object of his affection, and Dominic Cooper is Evans’ charismatic competition, A.J., who would go on to fame as artist Alfred Munnings, one of England’s best painters of rural scenes.

As for how the drama is going at “Downton Abbey,” Stevens said it’s been exciting to be back — and that new addition Shirley MacLaine has just completed shooting her scenes.

When he finishes the new season, however, he’s ready to move on from the past.

“I would like to do something modern and possibly funny,” Stevens says. “I seem to have not had many laughs for a while, so that would be nice.”
