Actress Margot Kidder says her stand against the Persian Gulf war didn't cause her to lose any roles but at least one job has been delayed. Kidder, in Toronto for a recent peace rally, was denounced in some quarters after making anti-war comments at a New York press conference, but she says she's received as much positive feedback as negative about her comments. "People have thanked me, coming up to me and whispering in my ear," said Kidder, who played Lois Lane in the "Superman" movies. She also says she hasn't been blacklisted by the entertainment industry but a charity did call her up to postpone filming an ad she was doing for them.
