It sounds like fans might not have to wait too long for Wonder Woman 2 to enter production.

A production listing for the highly-anticipated sequel was recently discovered on MyEntertainmentWorld (via OmegaUnderground). According to the listing, the film will enter production sometime in June of 2018, over a year prior to its December 2019 debut.

This early of a production date certainly isn't abnormal, as the first Wonder Woman film began production in November of 2015. But what's most interesting is the listing's 'Story' section, which claims that "the sequel will be a period piece, with Princess Diana facing off against the Soviet Union during the 1980s."

Rumors of the sequel being set in the Cold War first circulated back in July, but no updates have been provided in the months since. And recent comments from Warner Bros. Pictures chief Toby Emmerich, as well as the franchise's director, Patty Jenkins, haven't seemed to support or counteract that setting.

"I’d like to bring her a little farther along into the future and have a fun, exciting storyline that is its own thing,” Jenkins teased last month. “Wonder Woman 1 is so much about her becoming the person she is. I can’t wait to spring forward with who she is and have another great standalone superhero film.”

A lot is still unknown about Wonder Woman 2, from its villains to its potential new cast members. But if this production date is any indication, fans won't have to wait too long for their questions to be answered.
