Katharine McPhee Goes to the Movies  6/6/07

American Idol star Katharine McPhee is heading to Hollywood after signing up to make her movie debut in romantic comedy The Last Caller.

McPhee, who was runner-up in the U.S. talent show in 2006, will star as a self-obsessed woman searching for love and meaning to her life in the indie film, which she promises is a dark role.

The 23-year-old tells Billboard.com, "This is the first thing that I read that I really wanted to do.

"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."
