Is Smallville big enough for two Lois Lanes? We'll find out when big-screen Lois, Margot Kidder, guest-stars in the Sept. 22 season premiere the same episode that marks the arrival of teenage Lois Lane (Erica Durance). Kidder will play Bridgette Crosby, an emissary to Dr. Swann. Unfortunately, Kidder's Superman costar, Christopher Reeve, who originated the role of the mysterious doc, will not appear with her in the episode. But exec producer Miles Millar doesn't rule out a reunion later this season. "That's definitely something we'd like to do," he tells TV Guide Online.
