Anna Faris continues to surprise. She started off as just the unheralded, ditzy blonde in the "Scary Movie" franchise, and she then solidified her comic talents in movies such as "Just Friends" and "The Hot Chick" before showing a wider range in the acclaimed indies "Brokeback Mountain" and "Lost in Translation." Now, Faris hits this year's Sundance Film Festival with her new high-concept comedy "Smiley Face." And considering she plays the unmotivated, pot-smoking Jane, "high" might be an understatement.

"At times I felt stoned," Faris says as we sit down to discuss her new flick. "I mean, you think about glazing your eyes and not really focusing on anything for a long period of time and then hunching the shoulders over. I think you definitely take on something there."

Faris didn't get high to play her character -- we think -- but the movie's depiction of one day in this seemingly unmotivated Los Angeleno's life is certainly a doozy. Jane begins the day by discovering she owes her pot dealer (a very funny Adam Brody) money; she mistakenly (OK, not really) eats her roommate's pot-filled cupcakes (which make her almost manic); she has an acting audition she's in no condition for; and she may become involved with stealing a rare copy of Karl Marx's "Communist Manifesto." And that only gets you to midafternoon in the movie's plot.

"It's funny ... reading the script, you'd be like, 'This is perfect. This is exactly what it's like,'" Faris says. "But it's also a story about a girl who is really lost who has no passion for her life besides her bed. She lives for pot -- or a Dorito. But certainly not life or ambition or money or sex or anything that normal people [would strive for]."

If you're a Faris fan and can't stomach the quirky pot angle of "Smiley," don't worry: She's got a slew of new movies on the horizon. She's starring opposite Jon Heder and Diane Keaton in the upcoming comedy "Mama's Boy," and she recently returned from London where she just wrapped the indie "Frequently Asked Questions About Time Travel." She's also hoping to start production this spring on an untitled comedy about a former Playboy bunny's attempt to adjust to life outside the Playboy mansion ...

But as time runs out on our interview, I ask one more "Smiley" question: Was there anyone that inspired her wacky portrayal of Jane?

"I have a good friend who regularly goes to auditions stoned," Faris says. "The good thing is that [she's so stoned] she doesn't feel too rejected when she doesn't get the part."

And in this town, that certainly beats therapy.

"Smiley Face" opens nationwide this spring.
