I'm not sure where exactly I was first introduced to Barbara Gordon/Batgirl, whether via Batman: The Animated Series or the '66 show, but Batgirl's portrayal in the latter was always very iconic in my mind. And I'm sure it was especially iconic for kids growing up when the show was originally airing and particularly for girls.
RIP Ms. Craig, and thank you for helping bring Batgirl into live-action and making her as popular as she is today.
I wonder if she was able to do any recording for the animated Batman '66 movie before her passing ?
