Skarsgard will play Pennywise, the evil monster who terrorizes a group of kids in a small Maine town. Lieberher will play the leader of the group, who was portrayed by Jonathan Brandis in the original 1991 film.
New Line recently announced the movie, directed by “Mama” helmer Andres Muschietti, would bow on Sept. 8, 2017. Muschietti came on board following Cary Fukunaga’s departure from the project last year, and quickly turned around a rewrite of the script.
The studio plans two films, one focused on the children, and a sequel following them into adulthood when they return to their hometown to face the monster again.
Barbara Muschietti, Roy Lee and Dan Lin are producing along with David Katzenberg and Seth Grahame-Smith.
Lieberher had a breakout role opposite Bill Murray in “St. Vincent” and recently delivered another critically-acclaimed performance in Jeff Nichols’ “Midnight Special.”
He is also set to star opposite “Room” sensation Jacob Tremblay and Naomi Watts in Colin Trevorrow’s follow-up to “Jurassic World,” “The Book of Henry,” which bows in September.
He is repped by CAA and Dayton-Milrad-Cho.
