Linda Lovelace's son has praised the makers of an upcoming biopic for portraying his porn star mother in a "new light".

Amanda Seyfried plays the title role in Lovelace, a new film about the infamous Deep Throat star who became an anti-porn activist in her later years.

Lovelace's son Dominic Marchiano has now spoken out about the movie and thrown his support behind the filmmakers.

He hopes the film will educate viewers about why his mother was fighting for women's rights.

Marchiano tells Britain's The Sun, "I knew this movie was going to shed a new light on my mom's story. I am proud of my mom and hope it will create a new awareness on the subject matter... She was a survivor... and a wonderful person."
