A fifth film would likely have appeared 18 months to two years after the fourth. When "Batman & Robin" received negative reviews and failed to outgross any of its predecessors, and a $150 million Superman film was canceled three months before shooting began, Warner Bros. became unsure of its plans for the fifth film. The studio decided it was best to consider a live-action "Batman Beyond" film and an adaptation of Frank Miller's "". Warner Bros. would then greenlight whichever idea suited them the most. Schumacher felt he "owe the Batman culture a real "Batman" movie. I would go back to the basics and make a dark portrayal of the Dark Knight." He approached Warner Bros. to do "Batman: Year One" in mid-1998.
