The spinoff will most likely be focused on Wonderland, as originally planned. During Paley Fest Edward Kitsis announced that they had no plans to recast anyone, so right now it’s almost guaranteed that the Mad Hatter will continue to be played by Sebastian Stan. We’ll also be getting three new characters; Alice, Amahl, and The Knave. No word yet on who will be playing the new characters.
Shooting is planned to begin next month.
