Hamill says it was his son Nathan who turned him on to what his son believed to be "a reality show about vampires." "I was completely unprepared for what I saw, it was so incredibly clever and compelling," says Hamill, who makes his debut in next week's episode. "It had all the elements of a horror movie and yet, it combined the magnificent with the mundane. Who thinks of things like this? I had to stop it multiple times to really absorb what we had just seen. It's one of my favorite movies ever." Hamill adds: "When I heard they were making a TV series, I thought I needed to lower my expectations. Neither Taika (Waititi) nor Jemaine (Clement) was going to be acting in it, but I heard they were behind it so I remained hopeful. We saw the pilot and, not only was it on par with the film, but it added elements that I had never heard before like the addition of the energy vampire. The whole cast is one of the best ensembles in television history. I would've been happy just visiting the set, they certainly didn't need me to come in and mess it up somehow."
