Ares appears as a major antagonist in the live action Wonder Woman film. In Queen Hippolyta's story about Ares which she reads to Diana, Ares was condemned by the other Olympian Gods for his warmongering which led to him killing the Gods where the images show him killing Apollo, Artemis, Athena, Hades, Hestia, and Poseidon until Zeus drove him off of Mount Olympus with his thunderbolts. In his dying breath, Zeus created Themyscira for the Amazons and left them the "Godkiller" required to kill Ares should he rise again. This happens during World War I where Wonder Woman managed to slay Ares.
In this new continuity, Wonder Woman's origin is significantly changed and she is no longer a clay figure brought to life by the magic of the gods. Instead, she is the natural-born daughter of Hippolyta and Zeus. The earlier origin story was revealed by Hippolyta to be a ruse thought up by the Amazons, to protect Diana from the wrath of Hera, who is known for hunting and killing several illegitimate offspring of Zeus.
She is seen fighting the Metal Men at the beggining of the Movie. Wonder Woman is in charge of the organization of the Intergalactic Games. She is under pressure because she wants to impress the Ambassador Bek so she can get an invitation to spent a week with them, which she think will help in her preparation to be a Queen in the future. During the competition, she races agains Lashina and Bleez in the "Flying with obstacles" game. She wins despite Lashina constant cheating.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
