Supergirl soaring onto Smallville in season seven
Straight from the network -- "On Smallville, the seventh season premiere kicks off with the arrival of Supergirl, whose name is Kara, as Clark's (Tom Welling) 19-year-old cousin. She was born on Krypton and is the daughter of Zor-El, Jor-El's brother. Kara possesses all of Clark's powers and one he doesn't yet have ??? she can fly! Kara also has a strong, rebellious streak that puts her at odds with Clark, and puts her onto Lex's (Michael Rosenbaum) radar. In addition, she takes a romantic interest in Jimmy Olsen (Aaron Ashmore)."
Ouch, does this mean Allison Mack won't be back? I'm keeping my fingers crossed ... but some new superblood on the show might help shake things up. It's in danger of stagnating, and a young rambunctious super-powered girl might be the shot in the arm it needs. As far as casting goes, I'd personally like to see the feisty and adorable Ellary Porterfield from Hidden Palms in the role. Who would you cast as Supergirl? Besides say ...
