Wonder Woman may not be the end for Doctor Poison. Speaking to TheVerge, Elena Anaya -- who plays the mad chemist Dr. Maru -- revealed that could appear in sequel films.
Asked if she was contracted for more Wonder Woman films, Anaya said, "Yes, yes, yes. But I have no answer for that. As you know, when these movies are made, they ask you basically to marry them for the rest of your life. [Laughs] I’d be so happy to be back, to be able to be evil again. It’s so good, it’s so fantastic.”
As Wonder Woman drew to a close, Ares presented Diana with the opportunity to kill Doctor Poison, who had caused so much pain and suffering through her deadly chemical weapons. However, as Diana stood holding a tank above her head, Maru's porcelain mask fell from her face and revealed that she, too, was a victim of violence and war. This was enough to sway Diana, who turned and destroyed Ares instead. As such, Maru was spared and she fled from the scene, never to be seen again.
However, Maru's eventual reappearance may depend on the setting and story of the Wonder Woman sequel, which has not yet been officially announced. Diana may be immortal, but Maru is not, unless she somehow develops a potion to keep herself young. So, if the Wonder Woman sequel happens to take place in the modern day, it may be all-but-impossible to work Maru in in a feasible way.
Nevertheless, Anaya has plans for the character. "I think Dr. Maru has a lot left to do, and show, and tell," she shared. "She hides her femininity and vulnerability. It’s so easy for her to escape from every situation. She’s like a tiny criminal ant, it’s so difficult for her to be caught. She has many faces. You know, there is a moment in the movie when we see her face without the damage, and she looks like a fairly normal, easygoing chemist, like somebody who’s clever in her work. Who could tell that this person is going to invent the most destructive weapon ever? So I think Dr. Maru could have a nice side, and show it to the audience. It’d show a lot to the audience about evil people. About what I said about how they exist in real life, with a lot of power to changes everybody’s life."
Now in theaters, Wonder Woman stars Gal Gadot as Diana, Chris Pine as Steve Trevor, Robin Wright as General Antiope, Danny Huston as General Erich Ludendorff, David Thewlis as Ares, Connie Nielsen as Queen Hippolyta, Elena Anaya as Doctor Poison and Lucy Davis as Etta Candy.
