Piazza will play Clark Richards, "a brilliant, hyper-charmer with a restless energy, fierce intelligence and a dark sense of humor." He'll join a cast that includes Saved by the Bell's Mark-Paul Gosselaar, Saniyya Sidney, The Exorcist's Brianne Howey and UnReal's B.J. Britt.
The Passage is based on a bestselling trilogy of novels by Justin Cronin. It follows a woman named Amy Bellafonte (Sidney) as she fights to save the human race in a postapocalyptic America after a virus that turns people into vampire-like creatures has decimated the population.
Fox might be hoping this turns into its answer to The Walking Dead, but since it's a Fox show, it might turn into a show about vampires who solve crimes.
