This would help bridge the gap between Wonder Woman’s first solo adventure and her eventual appearance in Batman v Superman: Dawn of Justice.
Alas, we know very little information about Patty Jenkins’ second Wonder Woman film, so it’s all theorizing and guess work at this point.
Jenkins had previously stated that she was hoping to jump forward in time a bit, allowing Diana function in a more modern version of America.
And crafting another story that is set in the past will once again allow the movie to function independently from the rest of the DC Extended Universe.
