Fan Casting Doctor Harleen "Harley" Quinzell in Batman: Creature of the Night

Harleen is a psychiatrist and student of Dr. Leslie Thompkins, a childhood friend of Bruce Wayne's who treats him and conducts psychiatric sessions with him at Elliott Memorial Hospital. Harleen has had a secret crush on Bruce since adolescence, but since she began treating him, her platonic secret passion has turned into an obsession. However, she is constantly frustrated by Bruce seeing her only as a close friend and not noticing her attempts at flirting. Harleen is kind, intelligent, vulnerable, sweet, and flirtatious, but she can also be obsessive, possessive, and almost psychotic, as well as being extremely attention-seeking. At the end of the film, she gets a job at Arkham Asylum.
