TechRadar names Supergirl, Hamilton, 12 Angry Men among September 2026 4K Blu-ray picks

He said 4K Blu-ray is a major part of his work at TechRadar, both because he tests new releases each month and because it is his staple source for testing the best TVs and best soundbars, thanks to picture and audio quality he described as superior to 4K streaming. In the August 2026 most-anticipated list, he selected Project Hail Mary, Troy, West Side Story (1961), and Mars Attacks!.

Supergirl, from Warner Bros., stars Milly Alcock as Kara Zor-El, Superman's cousin, who teams up with an unlikely ally to take revenge against an alien evil while trying to save her dog Krypto. Jason Momoa also stars. The writer said the film has strong 4K potential because of vast space environments, bold colors, and space scenes that could show off a TV's contrast. The disc supports Dolby Atmos, which he said could make it an immersive showcase through fight sequences, big set pieces, height-channel effects, and room-rattling bass as Supergirl moves through the air. It is scheduled for release Sept. 8 in the US and Sept. 7 in the UK.

Hamilton, from Disney, is the filmed version of the stage musical about Founding Father Alexander Hamilton, with songs drawing from multiple genres, most notably hip-hop, and features the Broadway principal cast, including Lin-Manuel Miranda as Hamilton. The writer said the 4K disc's Dolby Atmos soundtrack should suit the production's scale, with hip-hop styles generating punchy bass and the array of voices testing a home theater's center speaker. Dolby Vision support, he added, should make period costume details and textures stand out, while stage lighting and shadows should create contrast-rich scenes. Its US release date is June 26, 2026, and its UK release date is Sept. 21, 2026.

12 Angry Men (1957) is being released by The Criterion Collection. The drama follows a 12-man jury deliberating a case in which an 18-year-old boy is accused of stabbing his father; 11 jurors agree, but one holds out, forcing the others to take a wider look at the case and evidence. The writer said he has high hopes for the Criterion 4K release, citing restorations of older titles such as Double Indemnity and 3:10 To Yuma. Dolby Vision is supported, which he said should benefit the black-and-white picture's contrast, while a good 4K restoration should give textures a refreshed and refined look. The disc only supports a monaural soundtrack, so he does not expect it to show off a home theater system, but he said Criterion has a knack for detailed mono soundtracks. Release dates are Sept. 8 in the US and Sept. 14 in the UK.

Star Wars: The Mandalorian & Grogu, from Disney, continues The Mandalorian TV series. It follows Din Djarin, also known as The Mandalorian and voiced by Pedro Pascal, and Grogu, who are tasked with saving Rotta The Hutt, voiced by Jeremy Allen White, in exchange for much-needed information. The writer said The Mandalorian is an excellent-looking TV show with plenty of detail and brilliant cinematography, and he expressed anticipation for the film's 4K release. The column did not include a release date for this title.

The column's headline also promised a fifth pick, describing it as "one of the most curious 4K releases I've seen."
