It was in October 1941 when wonder woman burst into the pages of comic books across America. Planting those first seeds of gender parity in the minds of fans and the world of superhe superheroes a woman can do everything a man can do. Now a larger than life actress is finally giving the 76-year-old superhero her big-screen debut. Here's ABC's Chris Connelly. Reporter: This weekend at movie theaters, the future is finally female. After years in gestation, wonder woman has arrived, giving its titular superhero W here heroine her time to shine on screen. From the origin female on the paradise island to exploits on the World War I battlefield. You certainly feel the pressure. This character means so much to so many. And you do feel the weight, the responsibility, by portraying her. Reporter: Yet it's sweet anticipation for wonder woman fans. And for 32-year-old star gal gadot. I feel like I'm standing on the diving board and I'm about to jump the highest jump. It feels like we've been working on this for three years and finally the baby's going to come out and it's just -- it's not going to be just me, just mine, it's going to be everyone's. Reporter: Five months pregnant with her second child during the film's reshoots. Gadot, who did two years of military service in her native Israel, says she sought to serve up a wonder woman both tender and tough. I wanted her to be very warm. Warm character. Very vulnerable. And full of hope and love. But you also kick a lot of -- Ass, I know. I was a fencer for 12 years. I always enjoyed moving around and doing choreographies and expressing myself with my body. Fighting is awesome, especially when you do it, you know, on such a big set with horses and with, you know, the rest of the women that were there with me, or men. Reporter: Or men. As the flying ace she rescues who leads her into early 20th century life. That's not going to work, please put the sword down. Reporter: And up to the front lines. Chris pine gets that this film has offered him insight into how the other half lives in Hollywood. You have to come out of the grotto and do a lot of the things we've seen women in your position having to do over the years. Yeah, yeah. You know, it's -- putting myself into a position where I'm objectified. I guess the novelty of it, I didn't mind it so much, I was like, well, screw it, it's about time, you know. Reporter: She spent more than three-quarters of a century in the comics, as both an objective male fantasy and as a proto feminist "Ms." Magazine cover subject, wonder woman's been best known by her TV series incarnation from the 1970s which played for three seasons bit universally beloved Lynda Carter. She shared her affection for the character in 2005 with ABC news. I got to tell you, I loved wonder woman too. I read the comic books. And I got to play her. I mean, how cool is that? Women are the wave of the future. And sisterhood is stronger than anything. We were building the bridges for young girls today. They were going to be in a world where it was okay to be smart, okay to be beautiful, okay to be feminine, okay to be strong, okay to be athletic. Reporter: Thanked in the feature films and critics, Carter had positive influences on the director Patty Jenkins. What were the wore values that wonder woman had that you were an advocate for as you set out to make your movie? I wanted her to not be a female superhero. She's a great superhero. And so the values were the balance, the goodness, the kindness, the positivity that she has always had and was created with. And Lynda Carter had done such a beautiful job of embodying. Reporter: It's Jenkins who conjures up the landscape populated solely by woman warriors. Robin Wright and gladiators Connie Nielsen among them. The most challenging thing I did in this movie was tone. A fantasy world to a period piece to a historical war context, which was surprising reality with a little bit of pop that made it feel like it lived up to the great graphic novel superhero genre comic books. I met with Patty Jenkins before there was even a script. What she explained to me that I really enjoyed is she wanted to make casablanca, a big old-fashioned romance under the guise of a superhero film. And she was given leeway to do that. Reporter: The costuming first seen in "Batman V. Superman." And due to turn up in such future films with DC comic characters as "Justice league," was key to her appeal. Just by wearing it and looking into the mirror, it's like -- it hits you, okay, all right. Now I got to play up to it. I had like seven or ten different costumes. For this movie. One is shinier, one is softer, one is heavier. So -- not that one. That's the comfy one. That's the comfy one? Exactly. Reporter: Comfy since wonder woman was shot during the dead of English winter. She took being wonder woman incredibly seriously and she would never let us down. If that meant she alone was running across a field in a wonder woman suit while I was wearing a snowsuit designed for the climbers of Everest, true fact. She would do it. It's true. Red, big, puffy coat. Onesie. That's what she wore. What I wore? You're asking? Oh, not much. Reporter: The same audience members whose hearts leapt to see Daisy Ridley wield the light saber in "Star wars: The force awakens." May find wonder woman giving them some long-awaited moments of thrills and exhilaration. We saw it in 3D and I'm not a big 3D fan -- You look pretty good in 3D now. Yeah. Once "Nightline" goes with 3D we know it's the end of the world, please don't do that, my god. The 3D was great. I'm telling you, there was this like collective -- palpable shift in the audience. Especially when gal comes out of the trenches and it's like the slo-mo shot. It was incredible, incredible. I was stunned by the audience reaction. It was mind-blowing. Reporter: Could be the fulfillment of a dream the star had well before she was cast. There was a big lack of true, real representation of women on film. Because usually we're the damsel in distress, we're the sidekick. We need to be rescued by the guy. And it's not the way it is in real life. In real life, women, we bring life. Little did I know that I'm going to land this role soon after. Reporter: For "Nightline," Chris Connelly, ABC news, los Angeles.
