Lovelace - the film that depicts the life of the famous porn star Linda Lovelace - has premiered in London.
Lovelace later broke free of the industry and worked to make sure other women were not exploited in the same way.
Amanda Seyfried, who plays the lead role, said her character found the strength to speak out against domestic violence and porn in general.
