Dunesday: Doomsday and Dune 3 both open Dec. 18

Avengers: Doomsday and Dune: Part Three open the same day, and Sony moved Jumanji: Open World to Christmas to avoid them. Dune: Part Three reportedly has a three-week IMAX window, while Doomsday's first two days of full presales in August ran about 65% ahead of Spider-Man: Brand New Day's pace.
