The actress looks like she took a time machine straight from the 1970s in a pink long-sleeved button-down shirt tucked into high waisted bell-bottom jeans, all cinched with a wide white belt.

She wears large glasses and sports King’s signature shoulder-length brown hair with heavy bangs.

Battle of the Sexes depicts the drama surrounding the legendary 1973 tennis match between King and Bobby Riggs, played by Steve Carell. King defeated Riggs in the match than became the most-watched television sports event of all time, and sparked an ongoing conversation about gender equality.

King was 26 years younger than Riggs at the time of the match, and both had their own issues to prove.

“King and Riggs were on opposite sides of a binary argument, but off-court each was fighting more personal and complex battles,” read a press release about the film.

“With a supportive husband urging her to fight the establishment for equal pay, the fiercely private King was also struggling to come to terms with her own sexuality, while Riggs gambled his legacy and reputation in a bid to relive the glories of his past,” it continued.
