The 31-year-old actress, who is pregnant with Muse frontman Matt Bellamy's baby, is believed to be in talks about taking the lead role in the film adaptation of Eric Danville's book The Complete Linda Lovelace.
And according to Deadline.com, Spiderman star James Franco is up for the part of pornographer Chuck Traynor.
A rival Lovelace movie, titled Inferno: A Linda Lovelace Story, is also being planned. Lindsay Lohan was originally due to take the role of Linda, but was replaced by Malin Akerman because of her recent rehab stint.
