During one of the behind-the-scenes featurettes included on this Blu-ray platter, director Ron Fricke describes his latest film as a 'non-verbal guided meditation on the cycle of birth, death and re-birth'. While this might sound terribly pretentious, the truth is that Samsara is one of the most striking hi-def experiences around. Shot entirely in 70mm, scanned in 8K and mastered at 4K, the detail and colour fidelity in the disc's AVC 2.40:1 1080p imagery is unparalleled. The accompanying DTS-HD MA 7.1 soundtrack also impresses with its rich tones and wide staging.
