Principal photography began almost two weeks ago on the "Wonder Woman" solo movie with actors Gal Gadot and Chris Pine having been spotted around Essex in the United Kingdom filming scenes in period garb. The Daily Mail has posted new photos of the pair from the filming, both actors decked out in military gear, which seems to confirm the talk that a good portion of the film will take place during the first World War - especially the propaganda posters which do come from that time.
