Harley Quinn creator Tim Gunn was inspired by a dream sequence in Days Of Our Lives, where Arleen Sorkin wears a jester costume.

Harley has also appeared in videogames, such as the Arkham series, where she has become the leader of one of Gotham’s biggest gangs.

In the comics, Harley and Poison Ivy are a canonical couple, rescuing Harley from the abusive, stifling dynamic she had with Joker.

Margot Robbie will reprise the role Harley Quinn in Gotham City Sirens, which will see her teaming up with Catwoman and Poison Ivy.
