Laura Vandervoort is Supergirl in Smallville, and Michael Cassidy now plays Grant Gabriel, editor of The Daily Planet.

Vandervoort, 22, is another Canadian actress for Smallville (the show is filmed in Vancouver) where she joins Kristin Kreuk and Erica Durance.

From Toronto, she has dozens of television credits, most notably on the cable series Instant Star, and she guest-starred in an episode of Mutant X.

Supergirl arrives in the Season 7 premiere. Her name is Kara and she is Clark's 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 - flying.

Kara also has a strong, rebellious streak that puts her at odds with Clark, and puts her onto Lex's radar. In addition, she takes a romantic interest in Jimmy Olsen.

Cassidy's character, Grant Gabriel, will be a hot-shot young editor who is brought in "to the get the gray out" of The Daily Planet and make it more accessible to younger readers. He will be featured in a seven-episode arc taking place in the first 10 episodes of Season 7.
