— Joss Whedon's "Dollhouse" is going to air on low-rated Fridays. The series was originally scheduled to air with "24" on Mondays. Instead, "House" will open the night, followed by "24." — "Terminator: The Sarah Connor Chronicles" is also moving to Friday and will serve as lead-in to "Dollhouse."Ruh-roh! As if to drive the bad news home, Fox has set Dollhouse's premiere date for Friday the 13th of February. Whedon's Firefly famously tanked when Fox scheduled it on Fridays, so perhaps those "Save Dollhouse" campaigns that sprung up when the series was first announced weren't so premature after all. Nerds, commence your letter writing campaigns; Fox, we hope you're prepared to be besieged with truckloads of desperate, Dollhouse-saving Bratz dolls.
