Les Miserables star Amanda Seyfried has admitted taking on the lead role in a new biopic of porn star Linda Lovelace was "risky".
The actress said: "It is risky and people did not stop reminding me of that. But I also really wanted a challenge. It appealed to me in that way."
The US rights to the film have been snapped up following its world premiere at the Sundance Film Festival in Utah.
