Everything Everywhere All At Once is a must-buy on 4K Blu-ray. | Image: A24Movie streaming services are fine, but as their respective libraries and monthly rates change, nothing compares to having the 4K Blu-rays of your favorite movies to play whenever you want. If you want to add some titles to your collection, several great films and box sets are selling at the lowest prices of the year, and some of our favorites are under $20. Unsurprisingly, many of the films we’ve included below will be great to push your entertainment center to its limits. These big price drops are here because of Amazon’s Prime Big Deal Days, the two-day sale that lasts through Thursday, October 9th, at 3AM ET /12AM PT.If you aren’t equipped with a 4K Blu-ray player, well, you’ll need one. You can use the disc drive of a Xbox Series X or PS5 to watch some 4K Blu-rays, but you’ll be much better served by a dedicated player that sacrifices fewer features (neither console supports Dolby Vision for movie discs, and folks on forums report that their disc drives are quite loud). Panasonic’s UB820-K is widely regarded as the best, most feature-complete 4K Blu-ray player under $500. I have the model just below it in terms of capabilities, the $299.99 UB420-K, which lacks Dolby Vision (yes, Dolby Vision support adds that much to the cost).Godzilla Minus OneThe 2023 film is presented here in glorious 4K, with visual effects so impressive that the film earned an Oscar at the 2024 Academy Awards.Where to Buy: $23.79 $14.99 at AmazonLord of the Rings TrilogyIt’s tough to beat the value of getting all three LOTR films in 4K (both the theatrical and extended cuts) in a single set for under $100.
