Dollhouse star Eliza Dushku

Joss Whedon said a lot of things his fans wanted to hear at Dollhouse's San Diego Comic-Con panel — and at least one thing that had many of the show's faithful viewers biting their nails.

Whedon kicked off the panel by raving that the staff he assembled for the Fox series' freshman run was "the best" first-season staff he has ever worked with. So expect no major changes there.

As far as on-camera talent, the auteur announced that at least two Whedonverse alumni could show up on Dollhouse. Alexis Denisof, aka Angel's Wesley, is a sure bet to guest star in multiple Season 2 episodes, he said. This past TV season, Denisof had a brief run on ABC's Private Practice.

Also — and as has been rumored ever since Terminator: The Sarah Connor Chronicles' cancelation — former Firefly cast member Summer Glau is on Whedon's wish list, though nothing has been set in stone yet.

Other familiar faces to watch for early in Season 2 include Felicia Day, who had a role in the first season's never-broadcast thirteenth episode, "Epitaph One" (and back in the day appeared on Buffy the Vampire Slayer).

Amid the cheers and woots, Whedon gave the show's fans pause when at one point he teased, "There is one trustworthy person in the Dollhouse — and I'm going to kill them." Was he casting a dark cloud over do-right Boyd? Kindly Topher? Former lawman Paul? Whedon let slip no clues.

All told, Whedon seemed positively bullish on Season 2. He thanked fans for running their TiVos amok (Dollhouse benefitted tremendously from DVR playback) and forecast only good things to come.

Taking a tiny dig at a certain NBC show's sophomore growing pains, he said, "As long as we don't send anyone to feudal Japan, I think we'll be OK."

Dollhouse premieres its second season on Friday, Sept. 25, at 9/8 CT.
