At the end of the first movie, the Losers Club swore a Blood Oath and promised they’d all come back to fight the creature if it ever returns. And after 27 years, it finally does.
Bill Skarsgard returns as Pennywise, and Isaiah Mustafa now plays Mike, the only member of their group to stay in town. He took a job at the library to keep researching how to defeat the creature, and he’s the one who summons the others back to Derry.
Bill Hader from “SNL” is Adult Richie . . . who Finn Wolfhard from “Stranger Things” plays in the flashbacks. Jessica Chastain is Adult Beverly, James McAvoy plays Adult Bill, and Jay Ryan from “Beauty and the Beast” is Adult Ben, the chubby kid who had a crush on Beverly.
Stephen King also makes a cameo in it as a shopkeeper who meets Adult Bill when he returns to Derry. He’s the one who grew up to be a novelist and there’s a running joke in the movie that Bill never writes a good ending to his books.
