Lynda Carter, Venus Williams surprise Wonder Woman 1984 crew during DC FanDome

DC FanDome didn't hold back on wondrous surprises during its Wonder Woman 1984 panel that kicked off the 24-hour comic book convention. Patty Jenkins (writer/director), Gal Gadot ("Diana Prince"), Kristen Wiig ("Cheetah"), Chris Pine ("Steve Trevor"), and Pedro Pascal ("Maxwell Lord") were all present, but so were a few special guests, like Lynda Carter (the live-action Diana Prince from the 1970s-era TV show) and professional tennis player Venus Williams.

"I'm beyond excited. I have been a fan of [director Patty Jenkins] from Day 1 when she was first attached to this [series]," Carter said. "When my daughter saw Gal as Wonder Woman, she said: 'Mom, I finally get it. I finally understand why everyone idolizes you. I finally get what Wonder Woman means to everyone.' Thank you, Gal. Thank you, Patty."

Not surprisingly, Gadot made clear that Carter's legacy and tenure with the character has played a pivotal role in getting the modern-day franchise off the ground.

"We think about you every day, Lynda, and we talk about you all the time, so this would not be a Wonder Woman panel, truly, if we didn't see your face," Jenkins said. "And like the first time I ever called you, Lynda, I said to you: 'I want you to know we're not here to reinvent Wonder Woman, and we're not here to do a new chapter of Wonder Woman. We just hope to take the torch and pass it forward.'"

Gadot added: "You are a true-life Wonder Woman and I [couldn't] be more grateful to have your guidance and to be able to call you 'Mama Bear' ... Now this thing is whole because you're here."

Wiig, who has never met Carter in person before, started to geek out, talking about how she watched the Wonder Woman show all the time as a kid and even had WW-themed Underoos.

Williams, on the other hand, showed up to ask a two-part question: who would win in a tennis match between Wonder Woman and Cheetah, and will they ever put aside their differences to play doubles?

"I think both of you would overcome your differences to play doubles against [Venus]," Jenkins said. "You guys against each other...?"

"I think Cheetah would win," Wiig answered. "Wonder Woman would have a gold tennis racket to go with everything and it would just be too heavy and I'm fast and I just think I would win."

The panel closed out with the reveal of a second trailer in which Barbara Ann Minerva (played by Kristen Wiig) makes the transformation into Cheetah.
