Actress Joely Richardson is so upset over an unauthorized biography about her famous family -- which includes mother Vanessa Redgrave, director Tony Richardson and late sister Natasha Richardson -- that she's planning legal action against author Tim Adler.

The actress (who'll co-star in the upcoming remake of 'The Girl With the Dragon Tattoo,') wrote an essay in the British newspaper The Telegraph, dismissing 'The House of Redgrave - The Secret Lives of the Theatrical Dynasty,' as "prurient, contemptible hackery."

"The articles reduced my parents to the labels of 'Bisexual Father and Marxist Mother,'" Richardson writes. One of her biggest complaints is the book's sensationalism that has inspired headlines such as "the day Vanessa Redgrave walked in to find her husband in bed with her father." That's an unconfirmed incident that Richardson calls both "silly as pie" and "highly defamatory."
Redgrave once famously denounced "Zionist hoodlums" from the Oscar stage when she accepted her award for 'Julia,' but now votes Liberal Democrat, according to her daughter. "Love her or loathe her she is undoubtedly one of the greatest actresses of all time," Richardson writes in the article, saying that her mother agrees her politics have often been "misguided."

Richardson concludes, "Why bother addressing these issues publicly? I'd prefer not to, but these 'statements' were issued publicly about my family. So I'm using the freedom of the press to respond with the truth. To newspapers and publishing houses I urge the use of fact over fiction, freedom of the press, and responsibility at all times."

Richardson is best known for her role on the cable series 'Nip/Tuck.'
