'Downton Abbey' Star Lesley Nicol Talks Filming Downstairs

Fancy dresses and spacious dining rooms only go so far on "Downton Abbey."

According to Lesley Nicol, who plays Mrs. Patmore, the cook, on the PBS series, the servants have a lot more fun than the high class folks.

We get told off quite a lot," Nicol admitted to Vulture. "It’s a different atmosphere than upstairs, which has nothing to do with the actors. They’re just more restrained upstairs because they’re filming in somebody else’ house, a fancy house with expensive stuff around. They can’t be too giddy. The servants are on a set, so we can be more ourselves. The spirits are high downstairs!"

Season 3 of "Downton Abbey" has seen its fair share of plot twists and cast shakeups, and more can be expected in Season 4 ... particularly with the arrival of Lady Mary's new boyfriend.

According to The Daily Mail, the role is a coveted one -- and the producers aren't giving it to just anyone.

"Some were too dark, some too blond, some too bland -- though a couple have been put on a shortlist that the producers and creative people will discuss," a source reportedly said. "The main criteria for him is that he should be posh -- and pretty."

The season finale of "Downton Abbey" airs on Sunday, February 17 at 9 p.m. EST on PBS.
