Downton Abbey star Jessica Brown-Findlay has revealed her wilder side in her debut feature film, Albatross.

The actress, 22, who plays Lady Sybil Crawley the hit ITV drama has ditched her corset to play a teen rebel in the low-budget Brit flick.

Speaking to Sky News’ Eamonn Holmes she admitted struggling writer Emelia is “very different” to Lady Sybil.

Brown-Findlay said: “She’s got that same guts that Sybil has – just in a much more overtly obvious way, she’s ballsy.

“She doesn’t have a filter system – if she thinks something, she says it. She doesn’t have that restraint that Sybil has.”

Filmed in the Isle of Man in just six weeks, Albatross is released later this month.

The coming-of-age comedy drama sees Brown-Findlay’s character take a job as a cleaner in a seaside hotel owned by a middle-aged author and his wife.

Emelia becomes friends with the couple’s daughter Beth, but has an affair with Beth’s father due to their shared love of books.

Brown-Findlay also suggested her Downton character was something of a rebel considering the time in which she lived.

“She feels the weight of the restraints of the times and being a woman but also believes it is not going to be like that forever.”

“She’s quite brave in that she is able to think forward,” she added.

Last month Downton Abbey, created by Julian Fellowes, won four gongs at the Emmy Awards, including best supporting actress for Dame Maggie Smith.
