San Diego- [People]- Despite circulating reports and Jenna Jameson’s hopes that the actress is just the right mix of sexy and mysterious, Scarlett Johansson will not portray the porn star in the film adaptation of her autobiography.

“Scarlett has never seen a script nor been approached about this project,” says a rep for the actress. “She also has no interest in playing this role.”

Speaking with PEOPLE at the Comic Con convention in San Diego this weekend, Jameson, 33, said she was smitten with the 22-year-old Johansson after seeing her Golden Globe-nominated turn in the 2003 film Lost in Translation.

“I remember thinking to myself, this girl has such a sexuality without even really trying to be sexy,” Jameson said. “I was like, ‘This girl could play me.’ ”

Though she has met Johansson only briefly, Jameson said the encounter left quite an impression. “I love her,” Jameson said. “She’s amazing. She’s smart, she’s funny. … She’s stunning.”

Jameson said it will be called Heartbreaker, based on Jameson’s 2004 book, How to Make Love Like a Porn Star, in which she detailed her rise to stardom in the adult film industry.

Casting is crucial, said Jameson, emphasizing that the film needs more than just a pretty face. “I don’t want someone who’s going to go in there and be like bouncing around,” she said. “I want someone who can bring some depth.”

It remains to be seen just how risqué the film will be. Asked if it will be explicit, Jameson replied, “It has to be. Not because we want to draw male fans. Because I want to tell the true story.”
