Porn star Jenna Jameson is hoping Hollywood stars Rachel McAdams and Sienna Miller will battle for the lead role in a movie about her life after Scarlett Johansson snubbed the part. Jameson is hoping to cast either Miller or MCAdams for the movie which charts her transformation from ballet dancer to stripper, before making it big in the adult film industry. Johansson was Jameson's first choice for the part, but the actress turned down the role, citing she had "no interest in playing this role." But Jameson remains hopeful she will recruit a Hollywood beauty for the film, based on her bestselling autobiography, How To Make Love Like A Porn Star. She says, "I think Rachel MCAdams is amazing, and Sienna Miller."
