Beam Me Up, Scotty!: Folks, nowhere in this movie does Batman say "Chicks dig the car"; it's what Robin says in in the Call Back to this movie in Batman & Robin. What Batman actually says is "It's the car, right, chicks love the car?"
Breakaway Pop Hit: U2's "Hold Me Thrill Me Kiss Me Kill Me". Inverted with Seal's "Kiss From A Rose" (it was released the year before, but only became a smash hit after its inclusion).
An unbilled Ed Begley Jr. plays Stickley while Jon Favreau has a small role as one of Bruce's assistants.
Comedian George Wallace has a brief role as Gotham's mayor.
Old Shame: Only if you read it out of context. Val Kilmer enjoyed working on this film and everyone involved and would have been interested in returning once his schedule cleared up, but (fortunately for him) Batman & Robin continued without him. But he was quoted as saying "I've done an absurdly commercial cartoon and now I'm more likely to get hired for a job I couldn't get hired for before because I hadn't done enough movies. It's so rare when an actor gets hired because he's right for the role, it just doesn't figure into it," and people assumed he considered this movie to be an Old Shame. The above quote would become ironic in Kiss Kiss Bang Bang, when Kilmer's character Perry says virtually the same thing to a would-be movie actor.
Tommy Lee Jones replaced Billy Dee Williams as Harvey Dent/Two-Face. The studio had to buy out Williams' contract, as his contract included him playing Two-Face, but the studio wanted to go with Tommy Lee Jones instead.
Playing Against Type: Tommy Lee Jones, who usually plays stoic Deadpan Snarker type characters, here plays Two-Face as an incredibly loony, off the wall villain the 1960s Adam West Batman style.
So My Kids Can Watch: Tommy Lee Jones signed on as Two-Face because it was his son's favourite character.
What Could Have Been: The original version ofBatman Forever, before it was edited to make it more family-friendly. Several of the cut scenes (notably "The Bat Must Die!" and Bruce's encounter with a giant bat) would appear in the music videos for the movie, and the comic book adaptation retains the deleted cuts while making it more violent, specifically the large pools of blood around the fallen Graysons.
The cuts also would have changed the chronology of scenes in the finished cut: The Batsignal seen by Bruce at Wayne Enterprises is being helmed by Chase in the final cut, but it would've originally summoned him to the bank after Dent escaped Arkham in the deleted opener (which would explain the sirens Bruce hears when he sees it), and the scene with Chase on the roof would've been slotted before the Batmobile chase where it climbs the wall.
What would have happened had Billy Dee Williams insisted on playing Two-Face?
On the DVD featurettes, Billy Dee points out that the chemicals would have made one half of his face lighter than the other, and that this would play into questions of race, or something.
Before Schumacher took over from Burton, Scarecrow was going to be in this one, and Brad Dourif had been penciled in to play him.
Another comic book fan lobbied to be director before Schumacher was hired. His name? Sam Raimi.
Rene Russo was in line to play Chase Meridian when it was still believed that Michael Keaton was going to come back to play Bruce Wayne/Batman, not Val Kilmer. She was replaced by Nicole Kidman because the producers weren't comfortable with the idea of having Batman's love interest be played by an actress rather significantly older than the actor playing him. This in spite the fact Rene Russo is only about five years older than Val Kilmer, who is about eight years older than Nicole Kidman. Plus, Margot Kidder was almost five years older than Christopher Reeve when they played Lois Lane and Clark Kent respectively in the Superman movies.
Schumacher also initially wanted Sandra Bullock to have a role in this movie.
Marlon Wayans was originally set to play Robin, having been attached to the role since Batman Returns, but was bought out of his contract. Leonardo DiCaprio and Scott Speedman were some of those who auditioned for the role of Robin.
As did Christian Bale. Notably, when Bale auditioned for Batman Begins, the Batsuit he wore in his screen test was the one Kilmer wore here. (That's right — Bale has sported Bat-Nipples.)
Before the helm was turned to Schumacher, Burton supposedly wanted Mickey Dolenz as the Riddler, complete with a question mark carved into his forehead, natch. Carrey was planning on shaving a question mark on his head, but scrapped it because he was due in court for his divorce proceedings.
