As previously reported by Heroic Hollywood, the first half of the film will take place during World War I while the second half of the film takes place during modern day.

It appears as though the soldiers in the film have just arrived back to the UK after fighting overseas, with signage claiming: 'French money exchanged here for officers and soldiers in uniform'.

England - principally London - is the movie's main filming base, along with France and Italy.

While Nicole Kidman was rumoured to play Wonder Woman's mother Hippolyta, it looks like she may not have come on board with that role seeming to be a good fit for House of Cards star Robin.

The film is being directed by Monster's Patty Jenkins and she will be the first woman to direct a comic book super-hero film.

Originally, the film was meant to be directed by Breaking Bad producer/director Michelle MacLaren but she was reportedly dropped due to creative differences.

She was seen for the first time in the lead female role in the recently-released trailer for the film.
