Lovelace trailer - Amanda Seyfried as notorious Deep Throat porn star Linda Lovelace

The first trailer for a biopic of Linda Lovelace, the notorious 1970s porn star who will forever be synonymous with Deep Throat, has been released.

The film, from Rob Epstein and Jeffrey Friedman, appears nostalgic for a lost era of disco, sideburns, flares and extreme hedonism. But it is also a very grim story about a woman who was a victim of extreme abuse, both on camera and at the hands of her ultra-sleazy husband, Chuck Traynor.

The Independent's film critic Geoffrey Macnab, who saw Lovelace when it was showcased at the Berlin Film Festival, says Amanda Seyfried excels as Linda in a very challenging role requiring her to change from a 21-year-old girl next door to the haunted and battered woman she becomes in the wake of her marriage to Traynor (Peter Sarsgaard).

It is among a slew of recent films about the sex industry, including Michael Winterbottom’s Look of Love, about Soho’s mucky magazine and strip joint ‘King’ Paul Raymond (Steve Coogan), and Joseph Gordon-Levitt's porn addict trying to become less selfish in Don Jon’s Addiction.

Lovelace is in UK cinemas from 23 August.
