This press release just swooped into my emailbox:

On Smallville, the seventh-season premiere kicks off on Thursday, Sept. 27 with the arrival of Kara, AKA Supergirl, played by Laura Vandervoort. Armed with a second-degree black belt, Vandervoort soars into Smallville, catching the eye of both young photographer Jimmy Olsen and budding-villain Lex Luthor. "We cast Laura because she is the embodiment of Supergirl - she has warmth, beauty and she can kick some serious ass," says Al Gough, executive producer.

This season on Supernatural, Sam and Dean Winchester get some help fighting evil in the form of two tough-as-nails female hunters. On Thursday, Oct. 4, Ruby, played by Katie Cassidy, the daughter of '70s teen idol and singer David Cassidy, joins the hunt for the masses of demons who escaped from Hell in the second season finale. On Thursday, Oct. 18, Lauren Cohan enters the fray as Bela, a mercenary who realizes there is a lot of money to be made in the supernatural world. "Ruby and Bela, each in their own unique way, are dangerous, ruthless, more bad than good; and they'll each prove big trouble for Sam and Dean," says series creator Eric Kripke. "We were excited to find both Katie and Lauren; they just popped off the screen for us, and they bring charisma and intelligence to their roles."
