Katherine Heigl's decision this week to take herself out of the running for an Emmy has fueled rumors she might be leaving "Grey's Anatomy."
Heigl, who earned an Emmy for her work on the show last year, took herself out of contention for this year's Emmy race because she felt her character, Dr. Izzie Stevens, had not been given adequate material.
Recently, Heigl signed on to star in and produce a movie based on the book "Escape" by Carolyn Jessop, the former Fundamentalist Church of Jesus Christ of Latter Day Saints member who fled the polygamous sect and helped convict leader Warren Jeffs.
While it is not unusual for TV stars to film movies during hiatus, insiders wonder if the deal following closely on the heels of her Emmy snub indicates that Heigl soon will be leaving the show, the New York Post reported.
ABC and "Grey's Anatomy" creator Shonda Rhimes were not commenting on Heigl's remarks, nor was her publicist.
