Carnivale Star Hasn't Heard Any Talks About Reboot or Revival To say that HBO's Carnivàle was ahead of its time would be a bit of an understatement, as the two-season series blended period drama with the supernatural in an immensely compelling way, with a number of successors going on to tap into that unique blend of storytelling with otherworldly concepts, as fans still bemoan its unexpected ending in 2005 all these years later. With a number of cancelled series making unexpected returns across a variety of streaming platforms, and with HBO recently launching their new HBO Max service, some fans would think it would only make sense to bring the series back, but star Nick Stahl says he hasn't heard of any reports of the possibility.
