The DC Extended Universe will really kick off in 2016, when both Batman V Superman: Dawn of Justice and Suicide Squad hit theaters - introducing several new characters to the blossoming franchise, between them. One of those new additions many comic book fans will be keeping a close eye on is Gal Gadot's Wonder Woman, who will first appear in Batman V Superman before headlining her own solo film in 2017.
Outside of a director (Patty Jenkins), screenwriter (Pan's Jason Fuchs), and one additional casting (Chris Pine as Steve Trevor), not much is known about that standalone film. More light ought to be shed on the project once production starts around November this year, though yet another rumor has emerged regarding the when of Diana Prince's (origins?) adventure.
Heroic Hollywood is reporting that Wonder Woman will explore two distinct time periods; the first half of the movie apparently takes place during WWI, while the latter half is set in the present-day. During the WB panel at San Diego Comic-Con 2015, concept art was shown depicting the Amazonian warrior standing over soldiers in either WWI or WWII, so it seems this rumor could have at least one good foot to stand on. It's also been speculated before that Wonder Woman scenes set during WWI will be partly filmed on location in Italy.
At the same time, it's also easy to see how the modern day part of Heroic Hollywood's report is plausible as well. It stands reason to believe that WB did not sign an actor of Pine's caliber to simply be a one-off. It's speculation on our part, but given Trevor's larger role in the comics (serving as a liaison to the Justice League, among other responsibilities), one can see how Pine will be sticking around the DCEU for years to come (when he's not making Star Trek sequels, that is).
Should this rumor turn out to be true, it paints an interesting picture for the storyline of the Wonder Woman movie. Earlier reports had suggest the entire film will take place in the 1920s, but this is the first we've heard of such a timeline divide. It would be one thing for the movie to incorporate Batman Begins/Man of Steel type flashbacks (which take place in WWI), but HH's report indicates the narrative structure of Jenkins' movie will differ from that format - and, in some ways, perhaps present even more of a challenge. How scenes during two different timelines come together could make or break the film, if this rumor is accurate.
It's certainly possible that Jenkins and Fuchs could find a way to allow such different sections flow together thematically in a Wonder Woman movie - again, assuming any of this is true to begin with (a dicey proposition with superhero film rumors). Like so many tentpoles these days, the DC movie have been shrouded in much secrecy, but the answers will come in time.
