During a fight at a TV studio, the camera operator switches the camera to "Fight Scene" and the camera tilts to the side in a "Dutch tilt," which was used throughout the Batman (1996) television series and film to depict the "crooked" hideout.
While confronting the villains, Batman says, "You wanna get nuts? Let's get nuts!" This is a line that Michael Keaton said in Batman (1989).
Adam West, Burt Ward and Julie Newmar all reprised their roles from Batman (1966). They represent the only major cast members of the 1960s television live action series remaining at the time of this film's production, with Cesar Romero (The Joker), Frank Gorshin, (The Riddler), Burgess Meredith, (The Penguin) and Eartha Kitt (Catwoman) having already died.
The artwork The Joker steals is of a clown that is an obvious nod to the mask that Cesar Romero in the Batman 1960s series and Heath Ledger wear at the beginning of The Dark Knight (2008).
While aggressively fighting the villains, Batman says, "This is an operating table, and I'm the surgeon." This was an iconic line from Frank Miller's comic "The Dark Knight Returns."
