apparently, Amy Acker is going to voice a character on the Justice League.
That's not all:
Morena Baccarin, who plays Inara Serra in the Firefly television series and upcoming Serenity movie, is providing the voice of Black Canary in Cartoon Network's Justice League Unlimited.
Black Canary will be featured in the Season 4 episode, "Double Date," which is written by Gail Simone. The episode also features Kin Shriner as Green Arrow, Amy Acker as The Huntress and Jeffrey Combs as The Question, along with some other guest voices to be announced.
Baccarin is one of several Firefly/Serenity cast members to lend their voices to Justice League Unlimited.
As previously reported, Nathan Fillion is voicing Vigilante and Gina Torres is voicing Vixen. Adam Baldwin is voicing a villain in the season finale.
