Franchise newcomer Kristen Wiig will play the villain Cheetah.
Jenkins confirmed Wiig for the sequel in March. The character first appeared in the comics in the 1940s and is one of Wonder Woman's greatest foes. There have been many variations of Cheetah throughout the years, but the most recent is Barbara Minerva, an archaeologist who is transformed into a cheetah-like being through an ancient African ritual.
TV's original Wonder Woman, Lynda Carter, might play a role.
Carter told Megyn Kelly in April that she has talked to Jenkins about possibly appearing in the film.
DC Entertainment president and "Wonder Woman" executive producer Geoff Johns shared a mysterious logo on Facebook last week that teased a 1984 setting for the sequel.
Jenkins also updated her Twitter photo header with the image, which further hints at a 1980s Cold War-setting for the film.
