Short of watching the film on Tarantino's personal 35mm projector, this 4K Ultra HD Blu-ray release is the ideal way to watch Once Upon a Time. in Hollywood's 4K disc lacks a Dolby Atmos audio track, it really doesn't need it – the disc's DTS-HD Master Audio 7.1 track is more than capable of handling the film's heavy dialogue scenes and terrific late '60s soundtrack. Meanwhile, the bright neon that peers out of the darkness in the film's night-time scenes shines with exceptional vividness. In particular, we noticed increased warmth on the film's 4K disc, with more emphasis on yellow tones that accurately represent the film's sunny Los Angeles setting. Hollywood's 4K disc also has a leg up in the form of color vibrance thanks to some terrific HDR10 and Dolby Vision color tuning. When compared to the package's accompanying Blu-ray disc, the film's 4K Ultra HD Blu-ray presentation shows significant improvements in sharpness and clarity, with the increased resolution offering magnificent depth and detail in Robert Richardson's spectacular photography.
