Amanda Seyfried in Lovelace.

In Lovelace, Amanda Seyfried does a decent job as the star of the infamous Deep Throat—who had one truly lousy husband in Chuck Traynor (a creepy Peter Sarsgaard).

Rob Epstein and Jeffrey Friedman have made a film that feels surprisingly short, especially considering that they show the story from two different angles. The movie builds up to Linda Lovelace’s big porn moment—and then re-covers some of the same ground, this time showing Traynor’s brutality.

Since the film is just 92 minutes, not much ground gets covered.

Still, Epstein and Friedman get good performances out of Seyfried and Sarsgaard, with Sharon Stone doing decent work as Lovelace’s angry mother. The film features James Franco in a cameo as Hugh Hefner, with small parts for Bobby Cannavale, Robert Patrick, Chris Noth and Wes Bentley.

Lovelace opens Friday, Aug. 9, at the Camelot Theatres (2300 E. Baristo Road, Palm Springs; 760-325-6565); and the Cinémas Palme d’Or (72840 Highway 111, Palm Desert; 760-779-0730).
