Ever since we heard that Amanda Seyfried would be playing infamous '70s porn star Linda Lovelace in the upcoming biopic Lovelace, we've been curious to see her decked out as a '70s porn star! Especially since there's a competing biopic called Inferno, which originally starred Lindsay Lohan, and has since been recast with Malin Ackerman.

So the question remains -- who will be the more convincing Lovelace? Take a look at these sexy, earthy '70s pics of a brunette-wigged Amanda and let us know what yout think.

Not a particular fan of the earth tones and unflattering '70s cuts, but if anyone can manage to look good in spite of all of the unfortunate '70s styles, it's certainly Amanda. The high-waisted denim and printed halters look pretty decent on her, if we do say so. No pics just yet of her in Linda's sexier phase, but surely those will come out soon.

The one thing that we're not crazy about?? That wig! Why does it look so fake?? Probably because we know it is... but still, it seems like the production could throw down for a nice-looking hair piece.

While the movie is filming right now, the production is dealing with some casting drama. After Demi Moore's troubling health problems occurred this week, Demi has dropped out of her role as feminist lawyer and activist Gloria Steinem in the biopic. But Chloe Sevigny has since signed on to play a feminist journalist in the movie.

Take a look at all the pics of Amanda as Linda Lovelace and let us know what you think in the comments below!
