United Kingdom, Sept. 17 -- Olivia Cooke had a "sexual awakening" the first time she watched Bad Santa.

The 32-year-old actress made the racy confession after her A Talent For Murder castmate Dame Helen Mirren described Billy Bob Thornton's 2003 comedy as her favourite festive movie.

She told Entertainment Weekly: "I had a very formative sexual, like, thing. I was... never mind...

"I had an awakening, watching Billy Bob in a jacuzzi. An awakening, yeah."

The dark comedy stars Thornton as Willie, who is a miserable alcoholic con man who dresses up as Santa and robs department stores on Christmas Eve.

During the movie, Willie has a relationship with Sue (Lauren Graham), which includes a romp in a hot tub.
