"There was a sense of fun in the original series, and I think we wanted to try and create three characters as distinctive as Kirk-Spock-McCoy with Kai-Stan-Xev (plus a robot head). I watched the show quite a bit when I was younger, and enjoyed some of its campier moments, i.e. "The Squire of Gothos". I also liked the one with the weird head in the sky that turned out to be Clint Howard."
