Athena immediately set Diana on a quest into Hades' realm to free the god Hermes. She descended beneath Doom's Doorway with Wonder Girl (Cassandra Sandsmark) and Ferdinand the Minotaur and was confronted by Zeus' alliance. Ironically, she might not have succeeded but for the machinations of her constant nemesis, Ares. Ares acted as a double agent and gained Zeus' trust, but when the opportunity arose, he killed his uncle Hades and assumed control of the Underworld. Diana then used Hermes' caduceus to revive him. Back on Olympus, Zeus asked for Athena's forgiveness, which she granted. Athena then also restored Diana's sight, but bound it to her own.
In May 2017, early tracking had Wonder Woman opening with $65–75 million, and possibly as high as $105 million. The film opened Friday, June 2, 2017, across 4,165 theaters and made $38.7 million on its opening day, including $3.7 million in IMAX. It was the biggest single-day gross for a woman-directed film, ahead of the $35.9 million opening Friday of Catherine Hardwicke's Twilight in 2008 and the biggest opening day for a woman-led comic book superhero film, ahead of Ghost in the Shell ($7 million). This included $11 million it made from Thursday previews, also the best start for a film directed by a woman, surpassing Fifty Shades of Grey's $8.6 million which was directed by Sam Taylor-Johnson, and the third-biggest of the year, behind Beauty and the Beast and Guardians of the Galaxy Vol. 2. Of that, $1.5 million came from IMAX screenings.
