The original Dune feature premiered on the HBO Max streaming service last year.

The film is based on Frank Herbert’s novel of the same name, which was originally published in 1965.

The book was previously made into a film by David Lynch in 1984, which failed commercially and critically.

Dune, directed and co-written by Denis Villeneuve, was well received by critics and fans alike upon its release.
