The fall season hasn't even officially started yet, and already a show has been cancelled.

The WB has pulled the plug on its unscripted/game-show hybrid "Studio 7" after, appropriately enough, seven episodes. Thursday's (Sept. 2) episode will be the show's last.

"Studio 7" debuted to a miniscule 1.65 million viewers in late July, and its ratings in the 9 p.m. Thursday spot haven't budged since. While it's unlikely that any WB show would make a big splash in that timeslot in the coming season -- opposite two Top 10 shows in "CSI" and "The Apprentice" -- keeping "Studio 7" on the air makes no sense.

Instead, the network will show encores of second-year drama "One Tree Hill" in the timeslot, beginning Sept. 30. A stand-up comedy special from "Blue Collar TV" star Bill Engvall (Sept. 9) and encores of new dramas "Jack & Bobby" (Sept. 16) and "The Mountain" (Sept. 23) will occupy the intervening weeks.

The WB also says it's moving the premiere of "Drew Carey's Green Screen Show" back a few weeks, to Thursday, Oct. 7. The show, which combines improv comedy with computer animation, had been scheduled to debut Thursday, Sept. 16, but would have faced the premiere of "Survivor: Vanuatu" on that night. New episodes of "Blue Collar TV" will also resume on Oct. 7.

In the meantime, a one-hour "Blue Collar" special, scheduled for Sept. 9, and repeats of the sketch-comedy show will fill The WB's 8 p.m. Thursday hour.
