I mean, Harley Quinn's origin story was quite similar in all the media, and it always amazes me because it has so much potential.

But most of the time it wasn't expanded. I wonder it could be used as the source material to make a drama thriller movie just like the 2019 Joker, whether it could be standalone or a spinoff of the Joker movie. Show the character's life and the whole process of her transformation, it would be quite amazing to observe.

The 2019 Joker movie featured Arthur as a sympathetic character in some degrees and used him to reflect Gotham's problem. I think it could work if Harleen fall in love with such a figure.

And Margot Robbie as a very good actress, certainly has the ability to deliver a great performance.
