Even though it's part of her job, Sienna Miller still worries what her daddy thinks about her sexy movie roles.
Sienna admits she is terrified of what her father will think of the explicit scenes in her new movie "Factory Girl."
The 24-year-old actress - who plays real life 60s "it" girl Edie Sedgwick in the film - performs some of the most raunchy scenes ever included in a mainstream film and was determined to make them as real as possible.
But Sienna even covered her eyes when she watched back the sequences because she's dreading the day her father sees them.
She revealed in an interview with Britain's Daily Mirror newspaper, "We wanted to make it realistic and I watched it thinking, 'Oh my God, my dad's going to see it!' And that was going through my head the whole time. But it was relevant to the story in that it's a movie about the 60s, and sex and drugs and rock and roll were a big part of that."
"We didn't want to hold back because it is a real film and it is a gritty film and there were a lot of shocking things and it wouldn't fit in the film if we had an unrealistic sex scene."
Sienna's steamy scenes are alongside co-star Hayden Christensen, who portrays rock star Billy Quinn.
