This is a fresh thread since the next series has been officially announced and we can discuss what has been revealed, including the guest stars who currently are:
- Mark Hamill (even though he's playing himself, he's also been Joker, and Batman's going to be a guest star, too...)
- Kevin Conroy as Batman
- Jaleel White as Steve Urkel
- Sia
- Halsey
- Bill Nye
- Neil deGrasse Tyson
- Kenan Thompson
- Wonder Woman
- Flash
- Sherlock Holmes
- Chris Paul
- Ricky Gervias
- Penn & Teller
- Weird Al
- Whoopi Goldberg
Also, Chris Bailey is a producer. Also working on the show, unless he's been removed (or WB just wanted to mention Bailey as the sole driving force behind the show), is Michael Ryan. (And another guy, but I forget his name.)
It will be airing soon.
