It goes without saying that fans of Dune should absolutely pick up its 4K Ultra HD Blu-ray, but we also recommend it to anyone who considers themselves a home theater enthusiast. Dialogue is clear and prominent, while Hans Zimmer's nerve-jangling score offers a powerful backdrop to the events unfolding on-screen. Just as epic as Dune's visual presentation is its sound, with an outstanding primary Dolby Atmos track that delivers fantastic directional audio, offering plenty of activity in the rear channels, along with a masterful use of Atmos' height channels (you will think Dune's ornithopters are flying right over your head). Despite this, Dune remains an epic spectacle to behold. Witness, for instance, the shimmering appearance of Arrakis's all-important spice, or the almost white-hot explosion that eventually bursts through House Atreides' force fields during the mid-film invasion scene.Īside from some very minor banding, the only thing that could be considered disappointing to videophiles about Dune's 4K disc is that its aspect ratio does not shift during IMAX sequences, opting instead to keep a panoramic widescreen presentation for its entire running time.

The inclusion of both HDR10 and Dolby Vision gives Dune excellent brightness, contrast and color vibrancy. Though Dune was not shot on film, its UHD presentation sports a nice layer of film-like grain throughout, which serves to provide increased texture to its costumes, sets and sandy landscapes. Shot at 4.5K and finished at a 4K resolution, Dune looks expectedly gorgeous on the format, with immense detail that soars with incredibly clarity. One of the most anticipated 4K releases in a long while, Denis Villeneuve's Dune arrives on Ultra HD Blu-ray boasting a spectacular video presentation and a reference-quality Dolby Atmos audio track.
