Is Gwen Christie the only super-tall actress people can think of for Big Barda? Talk about lack of imagination.
Barda needs to have height, but frankly she should also be hot and conventionally sexy. I'm sure plenty of people out there have a thing for Christie, but she's not my idea of sexy. Barda has always seemed basically like Wonder Woman, but maybe 5 inches taller. Diana is a fantasy woman, as is Barda. Christie just isn't attractive enough (apologies to anyone into her that way).
Elizabeth Debecki is perfect. She's almost the same height as Christie (Debecki is 6'2), but she's also damned hot and conventionally sexy. Hire a 5'9 actor as Scott Free and she'll tower over him. Debecki isn't as stocky as Christie (she has more of a lanky model figure), but nothing a protein diet and a few months in the gym couldn't fix. And she's an exceptional actress.
