Here we have some pretty major details on how the plot of the solo Wonder Woman movie could well play out, specifically in regards to the villains of the piece and what drives them.
According to Heroic Hollywood, Ares will be the chief baddie, using Circe as a pawn to get what he wants: an ancient Amazonian sword so powerful it could make him the God among Gods, and allow him to take over Olympus. Apparently his aim is to start World War III in order to feed off of the energy generated by the massive amount of death and destruction that would result, giving him enough power to gain possession of the sword. Ares sends Circe to keep Wonder Woman (Gal Gadot) and Steve Trevor (Chris Pine) busy, changing human men into beasts as she goes, and herself becoming a Chimera for the final battle.
There's also a mention of a certain Caped Crusader, who might just be watching things unfold from a distance. The theory is he'll confront Wonder Woman about what happened when he meets her in Batman V Superman: Dawn Of Justice, which will see Diana searching for the lost sword.
There's more at the link below so be sure to check it out. What do you think of these details? Sounds pretty cool to me, but of course even if all of this was accurate at one time, it's always subject to change. Sean Bean and Eva Green were rumored to be in the running to play Ares and Circe, but we haven't heard anything solid since.
Wonder Woman is scheduled to be released on June 23, 2017.
