Trivia: SPOILERS: Director Todd Phillips has defended the controversial ending, in which it is revealed that Arthur is not the Joker who would go on to fight Batman when he is stabbed and killed by another inmate, who then carves a smile onto his face. Phillips noted that the two films were called "Joker," and not "THE Joker," and stated that Arthur was the person who inspired the real Joker—presumably the inmate who killed him. However, this explanation was poorly received by fans, who felt duped.

Carrey also laughingly admitted that the huge paycheck he got was one of the deciding factors, especially because he "buys a lot of stuff."
Trivia: When Lacey Chabert turns on the TV for Jack, you see Lindsay Lohan onscreen. Lacey says, "Hmm, I went to school with a girl that looks like that." Lacey Chabert and Lindsay Lohan were in the Mean Girls movie together and were in school in that movie. (00:20:10)

Trivia: When the Xenomorph lands over Kay, director Fede Alvarez asked for a bucket of cold water to be thrown at Isabela Merced to obtain a better scare face. Isabela says she was not informed earlier that they were going to throw cold water on her, so the face you see in that scene is her real face of fright trying to catch air because of how scared she was.
Trivia: A fan created a poster of this film emulating the design of the musical's iconic poster.
