Talk about doing a 180. Amanda Seyfried can currently be seen singing as the wide-eyed innocent Cosette in Les Miserables. Pretty soon, the 27-year-old will be showing off her deep throat skills on the big screen in the Linda Lovelace biopic. Lovelace is scheduled to debut at this year’s Sundance Film Festival on January 22. If she’s half as good as she is gorgeous in the poster above, it should be a decent flick.

Lovelace boasts a stellar cast including a trio of Oscar nominated stars- Sharon Stone, James Franco and Chloe Sevigny. Also featured in the 70s porn film are Peter Sarsgaard, Adam Brody, Wes Bentley, Sarah Jessica Parker, Chris Noth, Hank Azaria, Debi Mazar and Eric Roberts. With such a star-studded roster, it’s a shame to lose any of them. As it turns out, when all the edits for the film were completed, one of the above’s part was left on the cutting room floor. Find out who below.

It’s none other than Carrie Bradshaw herself, Sarah Jessica Parker. The 47-year-old actress took on the role of iconic feminist Gloria Steinem in the film. After leaving the porn industry, Linda Lovelace became an anti-porn activist who later became affiliated with Steinham. Producers explained that they decided to end the film in 1980, the year before Lovelace and Steinham joined forces.

SJP was added to the cast late in the game. Demi Moore was originally tapped to play Steinem but dropped out of the project when she was hospitalized last January. Producers frantically scrambled to find a replacement. Enter Sarah Jessica Parker. I’m curious to know if they cut out Parker’s role because it wasn’t good. Given her late addition, I’m sure Sarah didn’t have enough prep time to do her research. Are you sad that SJP won’t be in the film? Are you looking forward to Lovelace? Sound off below.
