Warner Bros. continues production on the Wonder Woman movie ahead of its 2017 release, and there’s still plenty to be learned about the superhero strongwoman. The latest intel comes from Gal Gadot’s costar Chris Pine, who confirms the film will take us to World War I and keeps hope alive for a potential Lynda Carter cameo.

Speaking about the setting to the Toronto Sun, the actor said, “It’s a period we don’t see often; it’s usually World War II. Our costume design is incredible. We have scenes with, like, 500 extras all in period dress. I’d never been on a film with extras casting as beautifully done as it is here.”

Pine portrays Steve Trevor, typically seen as Wonder Woman’s war pilot love interest. He describes his character as “a rogue-ish, cynical realist who’s seen the awful brutish nature of modern civilization. He’s a worldly guy, a charming guy and it’s going to be a great, fun film. There are some incredibly deep, interesting and morally relevant themes.”

Robin Wright and Danny Huston also have roles in the film, and Gladiator’s Connie Nielsen was recently cast as Wonder Woman’s warrior queen mother. But inquiring minds want to know whether Lynda Carter, who famously played the heroine on the ’70s TV show, will feature in some capacity.

“If I could tell you that I wouldn’t, but I can’t,” Pine said in a separate interview with E!. At least it’s not a “no.”

Wonder Woman is scheduled for theaters on Jun. 23, 2017.
