I test 4K Blu-ray for a living and these are the 5 discs I'm most looking forward to in September 2026, including 'one of the most curious 4K releases I've seen'

September 2026 is set to be another big month for 4K Blu-ray, and I’ve already picked out my most anticipated discs which I hope to test as part of Blu-ray Bounty, our monthly column where we test out the latest 4K Blu-ray releases to assess their picture and audio quality.

4K Blu-ray is a big part of what I do at TechRadar, not only because I test the latest releases each month, but because it’s my staple source for testing the best TVs and best soundbars , thanks to its superior picture and audio quality to 4K streaming.

In last month’s August 2026 most anticipated 4K list, I picked Project Hail Mary , Troy , West Side Story (1961) and Mars Attacks! as the discs I was most looking forward to trying out.

Check out the August 2026 Blu-ray Bounty for my full thoughts! This month, I’ve picked four more discs that I hope could be a great fit for your 4K Blu-ray collection, and I hope to test as part of Blu-ray Bounty — plus a fifth disc that’s one of the most curious 4K releases in recent months.

As I’m based in the UK, the following discs are set for release in September in the UK.

Supergirl (Warner Bros) Supergirl , starring Milly Alcock as the titular hero, tells the story of Kara Zor-El (Superman’s cousin) who finds herself teaming up with an unlikely ally to take revenge against an alien evil, while trying to save her dog Krypto.

The movie also stars Jason Momoa.

Visually, Supergirl has a lot of potential on 4K Blu-ray.

There are plenty of vast environments throughout space that could look excellent on the right screen.

There are bold colors throughout (not just the blue and red of Supergirl’s outfit) and a number of scenes in space, which could show off a TV’s contrast.

Superman (2025) was a visual feast on 4K, so let's see if Supergirl can follow suit.

With Dolby Atmos supported, there’s plenty of opportunity for this disc to be another immersive showcase for your surround sound system.

There’s more than a few crunching fight sequences and big set pieces to produce some room-rattling bass, and the Dolby Atmos soundtrack should make excellent use of height channels as Supergirl whips around in the air.

Release dates US — September 8 UK — 7th September Hamilton (Disney) One of the biggest stage musical shows in recent years, Hamilton tells the story of Founding Father Alexander Hamilton, with songs throughout drawing from a variety of genres, but most notably hip-hop.
