Taking a high-risk gamble, ABC is planning to remove the character of Dr. Addison Montgomery-Shepherd, played by Kate Walsh, from Grey's Anatomy and place her in a new, as-yet-untitled series, the Wall Street Journal reported today (Wednesday), citing no sources. The newspaper said that series creator Shonda Rhimes has informed the Grey's cast about the project and will write a special two-hour Grey's episode that will would serve as a pilot. ABC, the Journal said, would likely air it during the May sweeps.
