Yes she did. Grace Fulton plays the younger Mary. They look very similar so some assume it’s one actress. I hope they give the superheroes names this time. Love it or hate, DC and WB are not going to used the name Marvel for any of these characters. For years they did in the comics but used Shazam for the comic titles and Marvel family names in the books. But they are not going to have those names on action figures. They need to finally pick something better than “Superhero Mary”!
