Sweet Home Alabama star Josh Lucas has been left scarred by sex scenes in his new movie after spending a day with nine naked women he'd never met.

The actor had to simulate sex for montage footage at the beginning of Death In Love and admits the seedy scenes left him feeling dirty and "strange".

Lucas, who plays a con man who craves crazy sex in the film, tells WENN, "One of the weirdest days of my life was the day my character put an ad on (website) CraigsList for 20 women from the ages of 19-65 for the sex montage scene.

"I filmed nine very hardcore sex simulation scenes with women I never met with all of us completely naked. At the end of the day I felt crazy! It's something that I think only porn stars actually do in their life when they come in contact with that many people on that level.

"You're sharing body fluids whether you like it or not, sweat and sensation. I could never be a porn star. I was shook up. I did not walk away from that thinking, 'Oh, that was fun.' It was very strange."

Lucas is now desperate to shoot a family-friendly film after playing his latest character: "I was a mess for 30 days. He's so full of pain and self-hatred. I was living that every day and rage and guilt and traumatic things and my body felt pretty whacked.

"At the end of the day I'd crawl away and my dreams were pretty weird."
