Another Supergirl comes to Smallville...
Helen Slater, who played Supergirl in the 1984 film, will play the aunt of Kara, Smallville‘s Supergirl, played by Laura Vandervoort. There’s no word as to whether she’ll have powers, yet, but her entrance is scheduled for the sixth episode of the season.
She joins the ranks of Super-exes who cameoed on the show, with Christopher Reeve and Dean Cain, who will play a villain in the fourth episode.
