Dave Callaham, co-writer of The Expendables starring Sylvester Stallone, will help Patty Jenkins and Geoff Johns write Wonder Woman 2.

The Hollywood Reporter says that Jenkins brought Callaham in after working well with him on another project, Jackpot. That was going to be her next movie, before she signed a record-breaking deal earlier this week to come back for Wonder Woman 2.

Wonder Woman 2 is rumored to take place in the 1980s during the Cold War. It’s scheduled for a December 13, 2019 release, though that will likely change.
