The writer, director and producer previously created the series "Buffy the Vampire Slayer," "Angel" and "Firefly," which, like "Dollhouse," had small but devoted followings. "Buffy" ran from 1997-2003, "Angel" ran from 1999-2004 and "Firefly" was canceled after just 11 episodes in 2002.
TVGuide.com said Fox took "Dollhouse" off its schedule for November sweeps this season after four episodes.
Starring Eliza Dushku, the show reportedly is expected to return Dec. 4 and run until its series finale is broadcast Jan. 22.
"I don't have a lot to say. I'm extremely proud of the people I've worked with: my star, my staff, my cast, my crew. I feel the show is getting better pretty much every week, and I think you'll agree in the coming months. I'm grateful that we got to put it on, and then come back and put it on again," Whedon said on his fan Web site. "I'm off to pursue Internet ventures/binge drinking. Possibly that relaxation thing I've read so much about. By the time the last episode airs, you'll know what my next project is. But for now there's a lot of work still to be done, and disappointment to bear."
