"Lovelace" is a biopic on the 1970s porn superstar Linda Lovelace (real name: Linda Boreman), who rose to fame in "Deep Throat," the low-budget hardcore sex comedy that went on to gross something like $600 million. Its story is based almost entirely on "Ordeal," Boreman's 1980 account of her career in which she claims to have been forced by her abusive, pimp-like husband Chuck Traynor to do the film. Yet dig a little deeper into Boreman's life and it becomes clear the only proper way to film this story would be like Akira Kurosawa's "Rashomon," from several different angles: The truth is hazy and the story changes depending on who's telling it.
