Scarlett Johansson Rumored to Play Grounded Poison Ivy in 'The Batman Part II'

A massive script leak circulating on Reddit suggests Scarlett Johansson may play a highly realistic, de-powered version of Poison Ivy in The Batman Part II.

The leak, which originated in the r/DCULeaks community before administrators deleted it, reveals that the former Marvel star will play Dr. Pamela Isley as a plant-obsessed serial killer.

This screenshot shows the specific details of the leak that quickly spread across social media platform X and fan sites. The leaked description outlines a very different take on the classic villain:

"Scarlett Johansson is the main villain – a serial killer with an obsession with plants. She uses toxins, so I think she's more a realistic take on Poison Ivy."

In May 2026, director Matt Reeves confirmed Johansson's casting in the upcoming sequel.

Early trade reports and fan theories assumed she would portray Gilda Dent, the wife of District Attorney Harvey Dent.

But the new leak outlines a plot where her character uses plant-derived biological toxins to assassinate Gotham's wealthy elite.

Her main targets belong to a secret organization led by Charles Dance's character, fueling speculation that the film will introduce the Court of Owls.

Fans are divided over this realistic direction for Poison Ivy. Some online commentators argue that a grounded, toxin-using assassin fits the dark, detective-style tone established in the first film.

Others express disappointment, stating that stripping Pamela Isley of her comic-accurate ability to control plants ruins the unique nature of her character.

Other casting rumors align with this shift in the story.

Inside reporter Jeff Sneider recently stated on The Hot Mic podcast that Sebastian Stan is not playing Harvey Dent. Instead, Stan will reportedly play the bald serial killer Victor Zsasz.

This rumored swap leaves the role of District Attorney Harvey Dent open for actor Brian Tyree Henry.

Sneider also reported that HBO is quietly developing a standalone Poison Ivy spin-off series.

This project would plant its roots directly inside Matt Reeves’ grounded Gotham rather than the main DC Universe run by James Gunn.

If the rumor proves true, the series could explore the biochemist's backstory and her eco-terrorist campaign against corrupt corporate entities.
