Gal Gadot says she based her 'Wonder Woman' character on Princess Diana

• Gal Gadot told Vanity Fair that she based her "Wonder Woman" performance on Princess Diana.
• She watched a documentary that described how Diana was "full of compassion."
• "That should be the Wonder Woman that we have," Gadot said.

"Wonder Woman" star Gal Gadot revealed she based her character of Diana Prince on Princess Diana.

At a Vanity Fair Cocktail Hour Live! event on Tuesday, Gadot said she watched a documentary about the late Princess of Wales that inspired her performance.

"I remember watching a documentary about Princess Diana ... and there was a part where they say that she was full of compassion and she always cared for the people," she said. "And that was like, ding, ding, ding, ding. That should be the Wonder Woman that we have."

Princess Diana was known for her activism and charity work, as well as her relatability as the "people's princess" - both qualities that Gadot wanted to incorporate into her version of Wonder Woman.

"I wanted to portray a character that people will be inspired by but also be able to relate to," she said.
