Clare Foley, who plays Ivy Pepper/Poison Ivy in Gotham, won't be returning for its third season.
The show is now looking to cast someone a bit older, and according to an insider, "Casting is underway for an actress in her late teens to assume the now-series regular role of the would-be eco-terrorist." Her role will also be larger than it has been in the past.
Also being cast will be someone who can portray Vicki Vale. They are looking for someone in their late twenties to play what is described as "an ambitious young journalist".
