Juliette Lewis, 'Terra Incognita' -- Video Premiere

The first thing you'll notice about actress-turned-rocker Juliette Lewis's new video for 'Terra Incognita' is that she's looking pretty fit these days, enough to warrant her getting into a hardcore 'Fight Club' scenario right off the bat.

"I do love the symbolism of fighting," Lewis tells Spinner. "The art of it, taking your hits, taking your licks, getting up again -- it's a central theme to me as an artist, especially being a crossover act, coming from film into rock 'n' roll. This is the first time we touch upon that uphill battle."

As the video progresses, Lewis starts to splice in concert footage for her own recent tours along with mixed martial arts fighters and a host of extras she rounded up via Twitter and Facebook. "This has been one of the joys in creating music. It's grassroots," she says. "The audience and artist, we feed each other. It's a dynamic I've really been hungering for."

Joining Lewis for the video is British actor Michael Des Barres and model Koji Helnwein, who plays Lewis's fighting foe.

The song is the title track from Lewis's 2009 album, where she worked with the Mars Volta's Omar Rodriquez-Lopes -- who can be seen in the video as well -- to create what she describes as her "weird record." This video certainly drives that point home, especially when you get to the part when pink flames seem to be shooting off the top of her head.

"I want to be the f---ing antithesis to all the f---ing pop tarts, to Lady Gaga and somebody who works with a pound of makeup and the costumes," she says. "Yeah, I work with costumes, but it should be raw. I like the idea of instead of promoting sex, you're promoting strength and vitality."
