20th Century Fox has pulled the plug on X-MEN helmer Brian Singer's two-year first look deal, now that the director has signed on to direct Warner Bros. SUPERMAN, reports HOLLYWOOD REPORTER. Singer's Bad Hat Harry production company, which was based on the Fox lot, was asked to clear out its offices. Singer, who is working on SUPERMAN out of the Warner lot, does not have a overall deal with Warner, despite his development of the remake of LOGAN'S RUN. Both Fox and Singer's management the William Morris Agency could not be reached for comment.
