Wonder Woman
Technically speaking, the first live-action appearance of Wonder Woman was the 5-minute-long 1967 TV pilot short film titled Wonder Woman: Who's Afraid of Diana Prince? starring Ellie Wood Walker. Then there was the 1974 full-length live-action movie starring Cathy Lee Crosby. Neither of the two were deemed comic-book-accurate, leading to a bad reception by the public.
However, then came the 1975–1979 Wonder Woman TV series starring Lynda Carter as Wonder Woman, who many of us remember fondly as the face of the iconic superwoman.
Today, the most recent incarnation of Wonder Woman is Gal Gadot, having starred in the 2020 movie titled Wonder Woman 1984. However, there’s a 2021 movie already complete—Justice Society: World War II—where the role of Wonder Woman is played by Stana Katic, but Gal Gadot is set to appear in three other movies in the next 3 years, one of which is currently complete, so it’s quite likely that she’ll keep the title of Wonder Woman for now.
