'Downton Abbey' Jessica Brown Findlay regrets 2011 topless movie scene

Jessica Brown Findlay hardly bared any skin for her breakthrough role as the privileged but progressive Lady Sybil on "Downton Abbey," but the 23-year-old actress does regret going topless for her 2011 film "Albatross."

In an interview with Radio TimesTuesday , Findlay said she didn't know she could turn down a topless scene.

"To be honest, Albatross was naivety and not knowing that I could say no," she said. "I had no idea what was going to happen and thought I was going to be shot from behind."

In the film, Findlay's character lifts up her top to prove she's old enough for cigarettes.

Findlay is still bearing skin for her next project, "Labyrinth," a miniseries for Britain's Channel 4, though she doesn't seem eager to do it again.

"If you're going to do a nude scene, be honest and natural. Otherwise I'd be starving myself forever, which I just couldn't do! The idea that actresses would work out at the gym for a thousand hours before hand ... I was drinking pints and eating burgers. But actually, it's not something I would do again."
