Người Dơi

Robin Williams was offered the role of Joker when Jack Nicholson hesitated. He had even accepted the role, when producers approached Nicholson again and told him Williams would take the part if he did not. Nicholson took the role, and Williams was released. Williams resented being used as bait, and not only refused to play Riddler in Người Dơi Bất Tử (1995) but also refused to be involved in any Warner Bros. productions until the studio apologized. His next project with the studio would be Fathers' Day (1997).

(at around 1h 2 mins) When destroying the paintings in the museum, one of Joker's henchmen puts several hand prints on a painting. Later, we see Joker imitating the statue, and in the background we can see the painting that had supposedly been fingerpainted is not.

The opening credits appear as the camera goes through/around a giant Batman symbol.

In order to put the 126m. movie in 120m. video cassette, South Korean video distributor cut two scenes when the movie was first released on VHS. The first one is a whole sequence where The Joker kills Vinnie Ricorso with a quill pen in front of the city hall. The second is the arrival of Batman on the rooftop of the cathedral and a few fight scenes with the goons. After the police sweeps the cathedral with searchlights, the scene abruptly cut to the scene where a goon with rope (the third goon that attacks Batman) desperately seeks Batman. Also, the initial South Korean DVD release has only widescreen version of the movie, so it featured a strange cut where Vicki pretends to tempt The Joker. This scene has been fixed on the special edition DVD.
