The DVD comes out early next year and includes 9 minutes of new footage, plus 'two documentaries, screen tests, deleted scenes, the screenplay with the director's notations, music outtakes, trailers and myriad other items.' The screen tests include Anne Archer, Stockard Channing, Lesley Ann Warren and Deborah Raffin auditioning for the role of Lois Lane.
