New this month Trivia: The use of "Rock and Roll Part 2" by Gary Glitter within this film caused controversy shortly after the film's release due to the perceived possibility that Glitter, a convicted sex offender, might collect royalties from the song's use in the film. This concern was unfounded, though, since Glitter had long since sold the rights to the song's use; the US rights are currently held by the Universal Music Publishing Group.


New this month Trivia: When Arthur practices his entrance at home to the show, the guest in that episode is the actor called Ethan Chase. Just like the made up actor name Zach Galifanakis gives himself in the Todd Philips directed film, Due Date.

Trivia: The font used for Live With Murray Franklin is identical to the Batman animated series titles.

Trivia: While the time period of the movie isn't explicitly stated, the movies showing at the cinema the Waynes are at (Zorro The Gay Blade, Wolfen, Excalibur, and Arthur) were all released in 1981, making that the likely year it's set. The Zorro reference is certainly a nod to established comic continuity, where the Waynes were watching The Mark Of Zorro.

Trivia: Towards the end while Joker is being transported in the police car, the shot of him through the window is similar to one of Heath Ledger's Joker in The Dark Knight.


Trivia: Director Todd Phillips has specifically said that he doesn't see this movie connecting with any other DC movies - it stands alone.

Trivia: Arkham Asylum is seen, albeit not named exactly that.


Trivia: The idea of the Joker being a failed stand up comedian comes from famous Joker comic "The Killing Joke", which tells one possible origin story for the character.

Trivia: While Arthur is getting made up to go on the TV show, with the mirror and the lamps you can see Batman's face.


Trivia: Arthur and Sophie go to a diner on Jerome Avenue. The Gotham TV series featured twin brothers, Jerome and Jeremiah, the latter of which ended up becoming the Joker in the series.

Trivia: The sequence of the Joker killing a person on TV was also seen in Frank Miller's graphic novel The Dark Knight Returns.


Trivia: Brett Cullen (Thomas Wayne) played a small role in The Dark Knight Rises.


Trivia: Actor Justin Theroux has an uncredited cameo as a celebrity guest on Murray Franklin's (Robert DeNiro) TV show.

Trivia: Arthur's dressing room for the talk show is 404. Batman #404 was the first section of the Batman: Year One storyline, covering the early days of Batman's crime fighting.

Trivia: The final makeup of the Joker was inspired by the serial killer John Wayne Gacy, who went by the name Pogo the Clown. The club Arthur performs at is called Pogo's too.


Trivia: Arthur's joke "When I was a little boy and told people I was going to be comedian, everyone laughed at me. Well no one's laughing now" is a near-direct copy of a joke from late British comic Bob Monkhouse.

Trivia: The guy in the Waynes' mansion that helps Bruce isn't named onscreen, but is credited as Alfred Pennyworth, the butler of the family and future helper of Bruce as Batman.


Trivia: During the riot scene towards the end of the film, the Joker stands up on the car and in the background you can see a billboard for a movie called "Ace in the Hole." This is a line which Heath Ledger's Joker said in the 2008 film "The Dark Knight."

Factual error: Based on the films being shown at the theater, the movies appears to be set in 1981. One of the TV commercials shows the Energizer Bunny, which didn't make its first appearance until 1988.
