Warner Bros. has spent over $3 million on advertisements for Wonder Woman, whereas they spent $2.6 million on advertisements for Suicide Squad.

Separately, Fandango also found that 92% of people surveyed said that they are looking forward to seeing a film that features a standalone woman superhero, and 87% wished Hollywood would make more women-led superhero films.

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.
