I
LOVE the show, even though it's obvious it is mostly meant for kids and is no way on par with the DCAU. But, several actors from BTAS, STAS, JLA & BB do voice overs on the show from time to time, including:
Kevin Conroy (Bruce Wayne/Batman - BTAS)
Mark Hamill (The Joker - BTAS)
Clancy Brown (Lex Luthor - STAS)
Dana Delany (Lois Lane - STAS)
Adam West (Simon Trent /Gray Ghost - BTAS)
Tara Strong (Barbara Gordon/Batgirl - BTAS)
Richard Moll (Harvey Dent /Two-Face - BTAS)
Jeff Bennett (HARDAC - BTAS)
Will Friedle (Terry McGinnis/Batman - BB)
Jeffrey Combs (Jonathan Crane/Scarecrow - BTAS)
Oded Fehr (Kent Nelson/Dr. Fate - JLA)
Loren Lester (Dick Grayson/Robin/Nightwing - BTAS)
Kevin Michael Richardson (Carlton Duquesne - BTAS)
Carl Lumbly (The Stalker - BB)
And those are just a few off the top of my head. Other actors in the show include:
James Arnold Taylor of The Clone Wars fame, he does voice work as Green Arrow.
Star Trek: TNG star Wil Wheaton voices the second Blue Bettle, Ted Kord.
The Clone Wars actor Dee Bradly Baker voices a slew of characters from Clock King to Scarecrow.
Back to the Future star Tomas F. Wilson voices Catman & Sports Master.
Transformers: Revenge of the Fallen voice actor Tony Todd is Asaroth.
Transformers veterin actor Tom Kenney (also known for his work on Spongebob Squarepants) does the voice of Plastic Man.
All in all, it is not DCAU, but it is one awesome show regardless and a lot of parts from the show do stick close to their comic book roots. I certainly enjoy it!
I highly recommend Batman fans check it out if just for a good time! You won't be disappointed!
