Later, Etta was released from hospital and Diana accompanied her to her home. She was shot by a sniper, but deflected the bullet and interrogated the attacker, who called herself Mayfly. She revealed that she had attempted to assassinate Wonder Woman in return for a bounty that had been placed on her. Shortly afterwards, Diana was attacked by five more assassins: Cat Eye, Cheshire, Abolith, Baundo and Plastique, the latter of whom revealed that she had planted the bomb at the wedding. Wonder Woman was able to defeat them all with the help of Etta, and they returned to an A.R.G.U.S. facility. There, Sasha Bordeaux informed her that another scientist, Hamilton Revere, had heard of Dr. Crawford's attempts to harvest Diana's DNA, and had apparently hypothesized that it could be used for the treatment of numerous diseases. Wonder Woman was intrigued and decided to seek out Revere of her own accord and hear out his plans. When she arrived, Revere informed her that in truth, he sought to use her DNA to create an army of super-soldiers. He had also used samples of Diana's blood to grant some of his goons super strength, who attacked her. Etta and Steve Trevor arrived to assist Wonder Woman, and together they bound the attackers in the Lasso of Truth, which once again removed the lie within their bodies. Revere was arrested, and Diana returned home with Steve and Etta.
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.
