Lindsay Lohan was like a "child lashing out" during filming for The Canyons.
The troubled star plays Tara in the upcoming erotic thriller and her 26-year-old co-star James Deen - who has filmed more than 4,000 porn movies - was taken aback at Lindsay's erratic behaviour on the set of his first mainstream flick.
He revealed: "There were days when she would scream and yell and cry and refuse to come out. In porn I am used to working with professionals who are courteous to others. But Lindsay was like a child lashing out."
It was recently revealed that Linsday, 26, was so keen to get her career back on track that she accepted a mere $100 a day for her role in the film - which follows "youth, glamour, sex and surveillance".
However, when she was expected to strip down for one graphic scene, the flame-haired actress is said to have lashed out "screaming".
Deen continued to the Sun on Sunday newspaper: "We were all standing round naked and the next thing Lindsay was screaming, 'Put your clothes on. For the love of God put your clothes on'.
"So we all put our robes on. But then she sat on the bed topless. When I asked her why she said she was 'allowed to'. With that I dropped my towel - and she stormed off set.
"She then refused to return until the entire crew stripped."
On another occasion Lindsay refused to remove her high heels, insisting she could do what she wanted because she was the "star" of the film.
Deen added: "It was a simple request. I am a short guy and it looked ridiculous with her towering over me in seven-inch heels.
"But she refused. She was crying and screaming that she was the star of the film. In the end it was decided I would wear boots to make me taller and she finally calmed down."
Although Lohan caused havoc on set, James couldn't help but notice how "fragile" the industry had made her, continuing: "She is a product of the Hollywood system. She is so fragile you can't help but feel for her."
