Los Angeles, March 9: Actors Shia LaBeouf and Stacy Martin carefully used prosthetics and porn doubles for intimate scenes in the movie "Nymphomaniac", about a self confessed sex addict recounting her life story.
"Neither Shia nor I were willing to actually have sex onscreen, obviously. Everything was set in place for us to have a porn double, a prosthetic vagina, special effects,"
Martin told Nylon magazine, reports femalefirst.co.uk.
"As actors, we could be ourselves and commit to an amazing project, but we were protected as human beings, and, speaking for myself, as a woman," she added.
The 22-year-old also said the script led to her and LaBeouf to have interesting conversations off the set.
She had earlier said that shooting the sex scenes got a bit boring due to their technical nature.
"It's not the most relaxing experience. It is quite strange, but also it is very, very technical. It almost becomes a bit boring because (director) Lars (Von Trier) gives you a lot of freedom when you're filming in general, and then suddenly you are restricted into doing certain positions and being very specific.
"Because they have to match everything together (with the doubles), you just have to really obey what they tell you. So you just have to get on with it," she said.
