Batman (film)/Trivia
- Actor Allusion: The infamous "let's get nuts" scene seems to be put in just to allude to Michael Keaton's role as a psychiatric patient in the comedy The Dream Team. His voice during that sequence is reminiscent of another crazy Keaton character.
- Jack Nicholson, playing a character sharing his first name who is driven insane by circumstances and famously goes Axe Crazy. And in his first appearance, Nicholson is sitting in a meeting shuffling a deck of cards.
- Billing Displacement: Jack Nicholson is the top billed actor, not Michael Keaton.
- Creator Backlash: A couple of months after the movie's release, Burton said that he felt the film as a whole was "mainly boring" and referred to it as "more of a cultural phenomenon than a great movie".
- Screenwriter Sam Hamm, one of the many writers who worked on the script, has also absolved himself from the sequence where Alfred leads Vicki to the Batcave, a move that didn't sit well with a lot of fans. Hamm said the scene didn't come from him and that the day Alfred let someone in the Batcave would be his last day of employment. It gets a Call Back in Batman Returns.
- The Danza: Jack Nicholson as (pre-Jokerization) Jack Napier.
- Enforced Method Acting: Keaton hated the Batsuit because he suffered from claustrophobia. Elfman and Keaton both decided that it would enhance his performance. And it did.
- Executive Meddling: This was a big reason the Schumacher films turned out the way they did, but again, Burton's films weren't immune.
- Meaningful Name: Jack Napier -- "jackanape" = "a joker".
- Playing Against Type: Comedian Michael Keaton as the Batman. Keaton himself lampshaded this in interviews with the observation that Bruce Wayne should be the person who looks least likely to be Batman.
- Prop Recycling: The doctor's tools were originally Orin Scrivello's dentist tools, and then perverse gynecological equipment.
- Shout-Out. Bob Kane, and those Little Shop of Horrors dentist tools sure get around a lot, since last appearing in Dead Ringers.
- The Corto Maltese War, mentioned here as being Vicki's last big photography project, is the name of the conflict Superman puts an end to in Frank Miller's The Dark Knight Returns.
- "I'm Melting" from The Wizard of Oz
- In addition to the general architecture of Gotham, the Climbing Climax bears a striking resemblance to the cathedral fight in Metropolis.
- Throw It In: When exploring Wayne Manor with Vicki, Knox (Robert Wuhl) ad-libbed the jokes aimed at Bruce's decorative collection of odd-looking armor.
- After the Board to Death meeting when the Joker tells Bob to tail Knox, Jack Nicholson ad-libbed his Grisson impression (complete with Jack Palance's breathy voice).
- Michael Keaton came up with the famous "I'm Batman" line - in the script it was "I am the (K)night".
- What Could Have Been: Sean Young was originally going to play Vicki Vale before Kim Basinger. Young had to bow out at practically the last minute after breaking her collarbone in a horseback riding accident.
