We interrupt your regularly scheduled weekend activities to bring you this urgent public service announcement: She'll be back!
Although Fox declined comment, multiple sources confirm to me exclusively that Terminator: The Sarah Connor Chronicles has been renewed for a second season.
You may now resume your regularly scheduled weekend activities.
Hopefully they'll increase the budget per episode.
