Joker is the title character of the first R-rated film to pass the billion-dollar mark at the worldwide box office.

Joker was originally supposed to be killed in his second appearance. -Batman from the 30s to the 70s (1970)

Conrad Veidt as Gwynplaine in the 1928 film The Man Who Laughs was an inspiration for the Joker’s appearance. -May 1994 Bob Kane interview with Entertainment Weekly/Frank Lovece

DC paid homage to The Man Who Laughs by publishing a retelling of the first Joker story, “Batman: The Man Who Laughs,” authored by Ed Brubaker and Doung Mahnke.

The first origin story presented for the Joker appeared in “Detective Comics” #168 (February 1951). This is the story that introduced Joker having been the villain known as the Red Hood.

Julius Schwartz, editor of Batman line of comics, despised the Joker and relegated him to comic book limbo in the '60s. Joker might have gone into obscurity had it not been for the Adam West Batman TV show where Cesar Romero’s version rose to icon status. Romero is also the first actor to play the Joker in a feature film (Batman: The Movie).

Heath Ledger posthumously won the Oscar for best supporting actor for his role as the Joker in The Dark Knight (2008). It is the first (so far only) time an actor won an Academy Award in an acting category for a role in a comic book movie. -Oscar Nominated/Winner Comic Book Movies - IMDb


When Joker was first created he was based on a 1928 silent film named ‘The Man Who Laughs’ starring Conrad Veidt’s character name Gwynplaine.

The first time Joker and Penguin team up was in Batman #25, for years they would team up together and Batman & Robin would defeat them!

Joker has killed many people since he debuted making his kill count huge. But in all film appearances (both animated and live action) ending at the Killing Joke. His total is 1,028 people.
That is already a huge number and it doesn’t count Suicide Squad or anything past that.

Tim Curry was originally cast as Joker in Batman: The Animated Series and recorded several episodes before being replaced by Mark Hamill. Though the writers said that his take on Joker wasn’t working for them, Curry has claimed that he was let go because he had bronchitis. (Source)
