Hmm, so only Brown, Conroy, Daly, and Pounder are reprising their former roles, though a number of WB Animation veterans are returning in different roles.
Alan Oppenheimer as Alfred? Cool! I haven't heard any voice work from him in over a decade, though IMDb says he's done a couple of shows I haven't seen and plays a character in the movie 9, which I haven't seen yet. Mostly he seems to do video games these days, as well as the occasional on-camera role.
And Michael Gough seems an odd choice for Hawkman.
