NEW YORK (AP) -- Lauren Anne Miller isn't afraid to talk dirty.
The 31-year-old actress stars in the racy romp "For a Good Time, Call ..." that she also produced and co-wrote with her former college roommate Katie Anne Naylon.
"You know girls ... we talk about sex and we talk about dirty things and in the writing process I loved any moment that I could write something that made Katie blush or be like, 'You wrote that?'" Miller said in a recent interview.
In the film, roommates Lauren (Miller) and Katie (Ari Graynor) start a phone-sex company in their New York City apartment. The story is loosely based on the pair's real-life friendship. (Naylon ran a phone-sex line out of her Florida State dorm room.)
But the script was finished before R-rated, female-centric comedies like "Bridesmaids" and "Bad Teacher" proved to be major box-office hits, so Miller and Naylon struggled to find a studio willing to take a risk on their bawdy flick.
"One day it hit me like a ton of bricks, and it was like, 'We need to make this happen for ourselves because no one is going to hand us this opportunity,'" Miller said.
They decided to produce it themselves, with family and friends helping get the film off the ground.
Graynor signed on as executive producer, as did Miller's brother Daniel, who helped find the funding. Miller's husband, actor Seth Rogan, appears briefly in the movie and her father helped in the writing process.
The film had a successful run at last year's Sundance Film Festival, and opened in theaters Friday.
"It's our baby," said Miller. "I like to say that we've been in labor for the past year and a half and this is our crowning moment."
