"Dune" initially hit streaming giant HBO Max on 21 Oct., 2021, one day before its cinematic release. The second film isn't set to follow in its predecessor's footsteps, however. "Dune: Part Two" will not be available to stream right away and will instead have an exclusive cinematic release. Though it's unknown when the film will have streaming availability, movies usually have a 30-to-45-day window between their theatrical run and hitting streaming platforms.
