Mamma Mia! Here's Amanda Seyfried In 'Lovelace'

Talk about a game changer! Sweet Amanda Seyfried is about to dirty up her image in the forthcoming Lovelace, a biopic on porn star-turned-activist Linda Lovelace.

In the just-released movie poster, Seyfried (who replaced Lindsay Lohan) certainly captures the 70s-style allure that helped make Lovelace's skin flick Deepthroat a national phenomenon.

The story, of course, goes much deeper than that, exploring Lovelace's eventual move toward demanding women's rights, blah blah blah.

Co-starring is James Franco as Hugh Hefner, Sarah Jessica Parker (replacing Demi Moore) as foghorn Gloria Steinem,  Peter Sarsgaard as her husband Chuck Traynor and Sharon Stone as Dorothy Boreman. *
