WATCH: "Wonder Woman" Unleashes First Trailer at SDCC

Appearing at Comic-Con International: San Diego, Warner Bros. debuted the hotly anticipated first trailer for "Wonder Woman."

The trailer starts with Diana discovering Steve Trevor on a shore, saying with surprise, "You're a man." Later, Trevor asks, "You've never met a man before? What about your father?" Diana responds, "I have no father. I was created by Zeus." Trevor: "Well, that's neat." Another exchange from the trailer sees Trevor saying, "I can't let you do this," and Wonder Woman replying, "You don't tell me what to do."

The newly revealed footage includes scenes of Amazonians fighting soldiers, and Hippolyta talking to her daughter, saying the man's world "doesn't deserve" her. It ends with the introduction of Lucy Davis as Etta Candy, describing the duties of a secretary with Wonder Woman saying, "Where I come from, that's called slavery."

Plus, the new electric cello "Wonder Woman" theme, which we heard for the first time in "Batman v Superman: Dawn of Justice," comes in just in time for the final shot.

Check out the "Wonder Woman" movie's first trailer below:

Before she was Wonder Woman, she was Diana, princess of the Amazons, trained to be an unconquerable warrior. Raised on a sheltered island paradise, when an American pilot crashes on their shores and tells of a massive conflict raging in the outside world, Diana leaves her home, convinced she can stop the threat. Fighting alongside man in a war to end all wars, Diana will discover her full powers...and her true destiny.

Directed by Patty Jenkins, co-written by Allan Heinberg and Geoff Johns, and starring Gal Gadot, Chris Pine, Robin Wright, Connie Nielsen, Lisa Loven Kongsli, Lucy Davis, Said Taghmaoui and more, "Wonder Woman" arrives in theaters on June 23, 2017.
