While Warner Bros. has not yet confirmed whether Jenkins will direct the sequel, ET's source reveals that she is helping to work on the film's script, which is set to take place between 1917 and 2017.
Jon Berg and Geoff Johns, who oversee the DC universe for Warner Bros., first revealed the news during an interview with Variety on Tuesday.
"Patty and I are writing the treatment right now," Johns said. "The goal is to make another great Wonder Woman film."
During an interview with Conan O'Brien earlier this month, Jenkins was optimistic about directing the sequel. "I hope to, I love it, I love the world, and we’re all really excited about it," she shared.
"It's amazing, because it feels like a long time coming and I know that I wished the movie had happened a long time ago, for many other reasons," she continued. "But, it feels like it hit this perfect pocket and I've loved that people have embraced it for that reason. And also, even the fact that Wonder Woman stands for love and truth, it's hitting home really hard that she is a superhero for everyone."
Wonder Woman has earned over $573 million worldwide so far, and was the highest-grossing domestic opening for a female director to date.
