My big question now if which cast members are returning? Hopefully they'll be able to at least get the main cast back.
I hope they can get all of them. It's generally easier to get people for voice work, because it takes less time and is easier to fit into a schedule, although sometimes there can be schedule conflicts with the recording dates (which is apparently why T.J. Miller reprises his movie role in
Dreamworks Dragons but is being replaced in the
Big Hero 6 TV series). And a lot of the YJ cast are people who do tons of voice work anyway -- Khary Payton, Jason Spisak, Danica McKellar, Crispin Freeman, Nolan North, Lacey Chabert, Yuri Lowenthal, Kevin Michael Richardson, Mae Whitman, etc.
When they did
The New Batman Adventures, they brought back almost all of the original cast. The biggest change was Tara Strong (Tara Charendoff at the time) replacing Melissa Gilbert as Batgirl. Otherwise we had Liane Schirmer replacing Ingrid Oliu as Montoya, Mel Winkler replacing Brock Peters as Lucius Fox, Jeffrey Combs replacing Henry Polic II as Scarecrow (a great improvement), Brooks Gardner replacing Aron Kincaid as Killer Croc, and Laraine Newman replacing Alison LaPlaca as Baby Doll. So only two major players and a scattering of bit players. Although there were a few later recastings in
Mystery of the Batwoman -- Eli Marienthal replacing Matthew Valencia as Tim Drake, David Ogden Stiers replacing Paul Williams as the Penguin, and Hector Elizondo replacing Henry Silva as Bane.
