Gotham Casts The Flash's Peyton List As The New Poison Ivy

The Gotham version of Poison Ivy takes on yet another form as the series casts former Flash and Mad Men actor Peyton List in the role.

The Gotham version of Poison Ivy is set to evolve yet again, as the series brings on former Mad Men and The Flash actor Peyton List to become the latest evolution of the character. The move makes List the third actor to take on the role as Ivy Pepper has undergone some dramatic changes since the series began. And according to the announcement by FOX, List's version will bring the character closer to the plant-controlling villain popularized in comics, cartoons, and video games.

List joins the cast roughly a season after Maggie Geha stepped into the role previously held by Clare Foley, who first played the part on the show. Foley's version of the character was a young child known as Pamela 'Ivy' Pepper until her involvement with the Dr. Hugo Strange storyline in season 2 saw the character mature rapidly. The sudden shift was meant to put Ivy on the path to becoming more of the vegetation-obsessed supervillain, which would make it easier to fit her into the series' ongoing storyline of classic Batman rogues running amok in a Gotham lacking a full version of the Dark Knight. That plan never really came to fruition, however, and now it seems Gotham is set to see Ivy Pepper transform yet again to begin her transition into a more comics-accurate green meanie.

In an official announcement from FOX, Gotham categorizes the casting as another step in the character's evolution and even hints at a future Ivy storyline that will see her powers come into play. The announcement says:

Gotham season 3 casts Poison Ivy

“In the continuing evolution of Poison Ivy's origin story, Ivy Pepper has been transformed once again taking another step toward becoming the Ivy we know from the comics. Dangerous. A live wire of crazy energy. She'll set her sights on Gotham, intent on making the city her own green paradise.”

Fans of comic book television will likely recognize List from her role as Lisa Snart/Golden Glider on The CW's The Flash. She's also starred in two other short-lived CW series, The Tomorrow People and Frequency, but List is perhaps best known for her role as Jane Sterling (née Siegel) in Matthew Weiner's Mad Men, where she played the second (and much younger) wife of ad man Roger Sterling, until their eventual divorce before the series' end.

List will help bring a sense of maturity to the character of Poison Ivy that was missing in both Foley and Geha's iteration of the soon-to-be villain, which was a source of both frustration for fans and fuel for critics. It will also finally see the character transition into what many had likely hoped to see when the series was first announced. The List version of the character is expected to first appear sometime in 2018.
