5) She Nearly Got An Earlier Movie Debut
As stated previously, Suicide Squad will at last bring Harley Quinn to the big screen. However, we could have already seen the character in cinemas a long time ago if all had gone to plan.
Before Batman & Robin crashed and burned in 1997, work had begun on a fifth Batman movie. Batman Unchained (also called Batman Triumphant by fans) would have seen George Clooney’s Dark Knight go up against an unholy alliance of Scarecrow (to be played by Nicolas Cage) and Harley Quinn.
Here, Harley would have been the Joker’s daughter, out for revenge after her father’s death at the hands of Batman in the 1989 movie. Rumour has it that Madonna and Courtney Love were both considered for the role at one point.
Who knows if any of this would have turned out well, but there’s no denying that it would have interesting to see such a radically different take on Harley than what we’ll be getting in Suicide Squad.
