A sharpshooter and ally of Steve Trevor. On his role, Bremner said, "I play a character who's enlisted by Wonder Woman to help save the world as part of a small, unlikely band". Describing his character, Bremner stated "He's a shellshocked soldier who's been discharged from the war and is brought back to help on a secret mission". On working with Jenkins, Bremner commented, "Patty Jenkins is a force of nature. She has fantastic vision, strength and enthusiasm, which is completely infectious and motivates a cast and crew of thousands to really go beyond themselves."
To find the perfect location to shoot the Amazon island of Themyscira, the birthplace of Wonder Woman herself, the film's producers searched all over the world, finally settling on the Cilentan Coast: a stretch of coastline on the Tyrrhenian Sea, located in the Province of Salerno in Southern Italy. It was chosen because most beaches in the world that sit below big cliffs disappear beneath the tide for part of every day. Production designer Aline Bonetto and her location manager Charles Somers considered 47 countries and visited several of them before they found what they were looking for. Bonetto explained that, "Italy had beautiful weather, a beautiful blue-green sea, not too much tide, not too much wave. Our effects team added some cliffs in post-production, and it was the perfect way to go". The estuary at Lower Halstow in Kent is featured in the scene in which Diana arrives at a Belgian creek to make her way to the warfront. Bill Westenhofer served as the visual effects supervisor for the film and Martin Walsh served as editor.
Thus although by the modern depiction her accomplishments at the time seem ordinary, in that era they were more so. Diana Prince was originally an army nurse, but quickly attained the rank of lieutenant in Army Intelligence. This was partially a creative convenience so that she could be close to both Steve Trevor and received information which she needed to pursue her superheroics. In the real world though, this role in Army intelligence, even as the secretary to General Darnell, was still a rare position for a woman to hold in society. At this time as well, the character had her only real sidekicks in her history in the form of Etta Candy and the Holliday Girls. These characters gave the Wonder Woman a degree more of levity while also allowing the writers to focus on some issues which were more related to women. When Marston left the character, the strong driving force of the character to act as a strong moral guide and role model for female readers left as well and the character became more sensitive to the forces driving the industry as whole. Thus Wonder Woman changed somewhat to a more stereotypical woman. Her main interest was not always fighting crime, but for a time it became all in the interest of keeping Steve Trevor happy and interested in her for marriage. Also the backup stories featuring the Wonder Women of History were slowly phased out and replaced with features on marriage customs from around the world and trivial facts on random household objects.
