Ever since Hulu announced Castle Rock, there's been a lingering question: just what would JJ Abrams' take on Stephen King's universe look like? You now have a better idea. Hulu has posted the first trailer for the series, and it makes more than a few references to King's many stories. Shawshank State Prison gets more than one nod, to start. Even the casting pays tribute. It star Bill Skarsgård shows up at one point, while Carrie's Sissy Spacek is returning to King's landscape -- albeit as a different character.
