What 2017 superhero film, starring Gal Gadot as the titular character, tells the origin story of an Amazonian princess who leaves her isolated island home to help fight in World War I?

The 2017 superhero film you're thinking of is, indeed, Wonder Woman. This acclaimed movie brought the iconic Amazonian princess to the big screen in her first solo live-action feature, with Gal Gadot powerfully portraying the titular character. The story delves into Diana's origin, showing her upbringing on the hidden island of Themyscira, a sanctuary for Amazon warriors. Her peaceful existence is shattered when an American pilot, Steve Trevor, crashes near their shores, bringing news of the "War to End All Wars" raging in the outside world.

Driven by a desire to protect humanity and believing the conflict is orchestrated by the god Ares, Diana leaves her home to join Steve on the front lines of World War I. This journey not only showcases her incredible strength and compassion but also explores her developing understanding of humanity's complexities, both its capacity for destruction and its potential for good. The film was praised for its optimistic tone and for presenting a strong, compassionate female hero.

Wonder Woman's cinematic debut was a long-awaited moment for fans of the character, who first appeared in All Star Comics #8 in 1941. Created by William Moulton Marston, a psychologist and inventor, Wonder Woman was designed as a feminist icon, embodying strength, truth, and justice. The 2017 film successfully captured these core tenets, offering a compelling narrative that resonated with audiences worldwide and solidified her place as a central figure in the superhero genre.
