Steve Blum, who has been done voice work in a million different projects, is in Star Wars Rebels. He was friendly and chatted with fans. I could overhear some of it and his fans were more interested in Cowboy Bebop or Ghost in the Shell.
As an added bonus, when he signed for me, he switched from his normal voice to Zeb’s voice (the character he plays in Rebels). It is fascinating how quickly he can change his voices. I smiled and left a happy kid.
