In the actual film, the Bat-Signal is first referenced when Superman lands in front of the Batmobile, causing it to crash into an empty warehouse, Superman tearing the car open to inform Batman not to respond the next time they shine his light in the sky. Later, believing Superman responsible for a bombing of Congress, Batman activates the Bat-Signal himself to draw Superman to Gotham to confront him, unaware that Lex Luthor is manipulating them both into combat so that Superman will either be killed by Batman's kryptonite spear or forever compromise his image by killing Batman to save his mother. During the battle, the Bat-Signal is destroyed when Superman throws Batman into it.
