I'm a 4K Blu-ray nerd and after trawling through Amazon's Prime Day deals, here are the 4 discs I'd buy

Sequel to the iconic Gladiator, Gladiator II starring Paul Mescal, Pedro Pascal and Denzel Washington is a great showcase for home theater systems, with its staggeringly powerful Dolby Atmos mix and stunning visuals. Definitely a disc for fans looking for some action.

An absolute cornerstone of my TV testing here at TechRadar, The Batman, starring Robert Pattinson and Paul Dano, is a visually striking movie that I use to test contrast and black levels on TV. Plus, its Atmos soundtrack, especially the Batmobile chase scene, is superb for testing soundbars thanks to its bone-rattling power and intricate detail. An essential for home theater fans.

One of my favorite trilogies of all time, Back to the Future starring Michael J. Fox and Christopher Lloyd, is the classic 80's time-hopping trio of movies that continues to entertain 40 years later. Benefitting from a solid 4K restoration and while it's not the home theater powerhouse of some other 4K Blu-rays, it's the best these movies have ever looked and sounded.

A masterpiece of modern cinema, The Lord of the Rings is one of the most beloved trilogies of the 21st Century (including this writer!). The 4K Blu-ray showcases these movies with how they were meant to look, with gorgeous visuals and a thunderous Dolby Atmos sound mix for the beautiful score and epic battle scenes.

John Wick, starring Keanu Reeves, is the franchise that succeeded beyond anyone's wildest expectations: and that's because it's just sensational action! These movies look amazing in 4K, with their nightclub sequences in particular a feast for the eyes. Action fans looking to show off their TVs won't be disappointed.

A cult hit of the 90's, True Romance starring Christian Slater and Patricia Arquette, is an action-packed romance/drama/comedy that delivers in all the right ways. This Arrow 4K restoration brings out the best details of this movie, giving it an uplift in picture quality.

OK, so there's no deal on this Tombstone 4K Blu-ray, but it is staggering how popular this 4K disc has been: and for good reason. I tested it as part of our Blu-ray Bounty feature, and it is a visually stunning restoration with beautifully updated visuals and a phenomenal and immersive Dolby Atmos sound mix that is great for showing off your home theater system.

Sony has released a 2025 version of its excellent 4K Blu-ray player, the Sony UBP-X700. It supports Dolby Vision and HDR10 HDR video formats, as well as Dolby Atmos and DTS:X audio. It has 4K upscaling for Blu-ray and DVD, plus support for a wide array of discs. We haven't tested the 2025 version of the UBP-X700, but if it delivers the same performance as the original, it's sure to be a top-notch player. This discount knocks a massive 27% off the price, which is a big drop considering it only launched a few weeks ago!
