Wonder Woman director Patty Jenkins has announced via Twitter that retired boxer Anne Wolfe, identified by Jenkis as "the best female boxer in history," is the film's Artemis. Jenkins made the announcement after a keen-eyed fan spotted Wolfe in the latest trailer.
In comic books, Artemis is part of a splinter tribe of Amazons called the Bana-Mighdall. She has been both an ally and a rival of Diana, even taking over as Wonder Woman for a short period. In the film, she appears to be one of the warriors that trains Diana to fight.
Wonder Woman is due out in theaters June 2.
