This might be the most interesting news we hear all week. Bill Skarsgard, who is playing Pennywise the clown in the upcoming IT movie has officially boarded another Stephen King adaptation. Castle Rock, the Hulu series that is based on King's multiverse, has brought Skarsgard on board as a series regular. The most interesting part? Bill Skarsgard is not playing Pennywise in Castle Rock. At least not as far as we know.

Variety broke the news that Bill Skarsgard, son of actor Stellen Skarsgard, is making his way to Castle Rock. According to their report, he will be playing "a young man with an unusual legal problem." That is pretty vague and doesn't give us a whole lot to work with in terms of being able to speculate, but this is a fascinating story nonetheless. Given the fact that this is the second current Stephen King project that Bill Skarsgard is going to be taking part in, that is at least worth raising an eyebrow. Especially when you consider what Castle Rock is.

Stephen King fans will recognize that the town of Castle Rock has been a major fixture in the author's universe for a long time. The town first appeared in the 1979 novel The Dead Zone and has appeared in several other novels since, including Cujo and The Body. The town also showed up in the stories Uncle Otto's Truck, Mrs. Todd's Shortcut, The Dark Half, The Sun Dog and It Grows on You. Point being, Castle Rock is a major fixture in the Stephen King multiverse. So bringing in the actor who is currently playing Pennywise is a big deal. Even if, as far as we know right now, he isn't going to play the IT character on the show.

Hulu has not yet set a premiere date for Castle Rock, but the show is expected to debut on the streaming service sometime in 2018. The cast is starting to come together, alongside the creative team, which includes J.J. Abrams as an Executive Producer on the series, with Sam Shaw (Manhattan) and Dustin Thomason (The Evidence) also on board as writers and producers. In addition to Bill Skarsgard, the cast for the series also includes Sissy Spacek, André Holland, Jane Levy and Melanie Lynskey.

Several months ago a mysterious teaser trailer for Castle Rock arrived online and referenced quite a few of Stephen King's works and characters, such as Creepshow, The Shawshank Redemption, Salem's Lot, Misery, Cujo and IT. In fact, Pennywise was specifically name-dropped in the teaser. That really makes this casting something to keep an eye on. If Pennywise is going to appear in the series, it makes sense that the producers, especially when you have a guy like J.J. Abrams involved, would want to keep something like that under wraps until the time is right. It is totally possible that Bill Skarsgard is actually going to have nothing to do with Pennywise in Castle Rock and that he is actually playing an entirely new character, but still. This show just became much more intriguing.
