Yeah, I noticed. It's probably actors and extras themselves who put their own names there. I remember plenty of those early-on when BvS's production was just starting. There were a "funny soccer mom", "crying Nairomian woman" and such. Yup. Not sure if they saw that on IMDB though, as she is a rather recent addition. I'd bet that she was added after that article mentioned her, but the logic is the same - lets disclose some new member of the cast, no matter how small the part or unknown the actress is.
