Eliza has posted an interesting titbit on her official Twitter about filming Dollhouse — filming commenced 2 weeks ago! — which suggests that Amy is either in the season 2 opener and/or the 2nd episode.
Joss is still awesome, Amy Acker & I may make out nxt up, & enticing Tahmoments lurk ahead post Comicon..!
In other news, Ausiello has confirmed that Amy will indeed be returning for 3 episodes! Happy news!
Comic-Con news alert: Dollhouse boss Joss Whedon just confirmed to me that Amy Acker has inked a deal to return for three episodes in season 2. There was some question whether Acker would be able to juggle Dollhouse with her full-time gig on ABC’s new drama Happy Town.
