Nothing is confirmed however, and Carter admits that she is not sure what role she would only have, saying that that is up to director Patty Jenkins.
“I’ve been talking to her about it. She’s given me some hints about it and I guess it’s up to Warner Bros. if they want to spend the money,” she said. “It really is up to Patty, and if it works in an organic way it’ll be great fun and it’ll be wonderful to do.”
Carter played the Maid of Might back in the TV series which ran from 1975 until 1979; it was simply called Wonder Woman in its first season, which was set during World War II, and The New Adventures of Wonder Woman in its last two, which were in then-modern times.
Wonder Woman (real name Diana, a princess from the Amazon island of Themiscyra) has been underrepresented in adaptations, at least compared to her DC Comics colleagues Batman and Superman. She is played by former Israeli model Gal Gadot in the DC Extended Universe, whose film last year proved to be the franchise’s only unqualified success. Before that, Carter’s show was the only real live-action depiction of the character, save for some TV series that did not get past a pilot.
Carter has several roles that act as Easter eggs for her former status as the best-known actress for a superheroine: the president on Supergirl, Chloe Sullivan’s mom on Smallville and the principal of a superhero school in Sky High. What role she may have vis-a-vis her successor remains to be seen.
