Oscar-winner Reese Witherspoon has fired her Hollywood agents at Endeavor and moved over to Creative Artists Agency (CAA). The move is the second agency switch for the actress since the retirement of longtime agent STEVE DONTANVILLE, who discovered and signed Witherspoon when she was 13. While at Endeavor, she made the upcoming thriller RENDITION, starring Jake Gyllenhaal and Meryl Streep and signed on for the remake of BUNNY LAKE IS MISSING. A source tells veteran Hollywood columnist NIKKI FINKE Witherspoon's recent split from husband Ryan Phillippe could have played a part in her decision saying, "Going through a divorce causes people to do a re-examination." The Walk the Line star is considered to be one of the most sought-after actresses in Hollywood where she commands an average of $15 million (GBP8 million) per picture.
