Live chat in March with Carnivale creator Daniel Knauf:
fboffo_DKnauf: Tiberius, this story is NOT done. I have four more seasons arced out. You might call the end of this season the end of the first "book."
fboffo_DKnauf: A trilogy, 2 seasons each.
fboffo_DKnauf: And you can quote me on that.
fboffo_DKnauf: And I bet you do.
So even though HBO has cancelled further seasons of Carnivale I'm involved in a huge campaign to keep it going. All of the actors and production crew involved with the show very much want to continue it, so we are going to fight for them. If Carnivale ever makes a return I can't express the joy it would bring.
