More than a year after she first began talking about it, Katharine McPhee is reportedly ready to make her leap to the big screen.

The American Idol fifth-season runner-up is set to star in The Last Caller, a "dark romantic comedy" that is scheduled to begin filming in and around New York in the fall, The Hollywood Reporter reported Tuesday.  McPhee will reportedly play a self-obsessed woman in-search of love and the hope of finding herself in the "coming-of-age" independent film.

"This is the first thing that I read that I really wanted to do," McPhee, who first began gushing about wanting to become a big screen actress immediately after losing last year's Idol title to Taylor Hicks, told The Hollywood Reporter. "I'm up for a couple of big studio projects, but they weren't starring roles. I wanted to start off doing something a little different. It's something that a lot of people wouldn't expect me doing."

Last August it was rumored that McPhee, who was being considered for a film version of Wonder Woman, but she discredited those reports shortly thereafter, claiming the prospects for a Wonder Woman movie weren't very good.  However the 23-year-old Southern California native has apparently found the right role with The Last Caller, which was written by Michael Albanese, according to The Hollywood Reporter.

"[The role] is definitely a little darker than me," McPhee told The Hollywood Reporter, which added the former Idol 5 finalist won't be required to sing for the film.

The Last Caller, which is expected to have a budget somewhere in the $5 million to $8 million range, is being produced by Hit and Run Productions' Hilary Shor and Zenith Film Group's Nicholas Cokas, with Robert Hawk serving as associate producer, according to The Hollywood Reporter.

In addition to performing weekly in-front of millions of viewers while competing on Idol, McPhee played herself in an early February cameo appearance in an episode of ABC's Ugly Betty.
