So dropping Professor Pyg in favor of an Ivy movie? I don’t know the original story being referenced but a quick read on Wikipedia, and I could see it being a cool take on Pamela Isley.
I still like the idea of Jonathan Crane / Scarecrow being Hannibal Lector in a Silence of the Lambs-type film with Barbara Gordon as the Clarice stand-in:
To help catch a serial killer terrorizing Gotham City, FBI trainee Barbara Gordon interviews her college psychology professor Dr. Jonathan Crane in the hope that he may help uncover the identity of the elusive killer, unaware of her mentor’s obsession with fear as the sadistic Scarecrow.
