Scarlett Johansson

Scarlett Johansson has laughed off claims she will play porn star Jenna Jameson in a Hollywood biopic.

Jameson herself prompted reports at the Comic Con convention in San Diego, California in July, when she said of the actress' performance in Lost In Translation, "I remember thinking to myself, this girl has such a sexuality without even really trying to be sexy. I was like, 'This girl could play me.'

"I love her. She's amazing. She's smart, she's funny. ... She's stunning.

"I don't want someone who's going to go in there and be like bouncing around. I want someone who can bring some depth."

But Johansson knows nothing of the film project - based on Jameson's book How to Make Love Like A Porn - which is to be titled Heartbreaker.

Her representative tells People.com, "Scarlett has never seen a script nor been approached about this project. She also has no interest in playing this role."
