“The Andromeda Strain” on 4K UHD Blu-ray is presented in a 2.35:1 aspect ratio with Dolby Vision or HDR10 form of high dynamic range. The movie was shot on 35mm film using Panavision cameras. It employed Panavision anamorphic lenses. It was presented in the Technicolor process, according to the film’s opening credits and IDMb.

This uses a 4K restoration from the original camera negative by Arrow Films. The original 35mm camera negative was scanned at 4K at EFilm, Burbank. The film was graded on Digital Vision’s Nucoda Film Master and restored at R3Store Studios in London.

Next, let me get technical, examining the 4K UHD Blu-ray Disc itself here. This 4K release uses a BD-100 (100 gigabytes) disc, 91.81 gigabytes total, and 84.8 gigabytes for the film. Based on observations, made using my 4K UHD Blu-ray player, this seems to peak at around 127.3 Mbps. It then runs roughly around 87.8 Mbps and dips down as low as 67.2 Mbps. According to info on the PC side, this 4K seems to have an overall video bitrate of 86.4 Mb/s average for the film.

Next, I want to visually compare the 2019 Blu-ray and the new 2025 4K UHD Blu-ray. The releases are from Universal Studios Home Entertainment and Arrow Video. Click on the text below to view more Blu-ray VS. 4K screenshots.

So, looking back at the previous 2019 Blu-ray in comparison to this new 4K, you will notice some things. First off, the color timing has ever-so-slightly changed with the addition of HDR grading. This change results in a more accurate representation of flesh tones. The 4K presentation can seem just a tad bit darker than the original Blu-ray. In comparison, it comes with more realistic shading and lighting conditions. Also, the black level feels more solid this time around.

There is certainly a nice amount of newfound detail to be found now, especially in facial close-ups. The overall amount of detail that you’ll see here in comparison to the original Blu-ray is relatively impressive. The amount of visible film grain left intact here is very satisfying to any purist.

“The Andromeda Strain” on 4K UHD Blu-ray, in this limited edition set, looks the best ever now on home video. It has never looked better. It feels very theatrical now in 4K resolution with the addition of high dynamic range. For a 1971 film, this looks great and serves as a very nice improvement in terms of video. That said, it earns itself a respectable 4.75 rating for video quality.

“The Andromeda Strain,” released in 1971, was a good film adaptation of the novel written by Michael Crichton. It still proves to be intriguing and disturbing to this day. The cinematography is excellent. The direction is especially great from a very well-accredited director for his time (Robert Wise). The film included a great primary cast of four actors. They played wonderfully off of one another. And the special effects, for their time, were pretty impressive.

The film was nominated for two Oscars (Academy Awards) for best art direction/set decoration and best film editing. The movie was reported to have been shot with a budget of around 6.5 million (according to Wikipedia) and ended up grossing 12.4 million overall at the box office. That’s not too bad of a return for the studio [Universal] here on this film.

The video quality is from the very same 4K transfer as the original 2019 Arrow Video Blu-ray release. This new UHD release fully showcases the 4K restoration work. The addition of HDR strongly enhances it. The color palette has changed just a tad bit. Flesh tones feel more realistic here in their accuracy. The overall presentation feels much more detailed. It brings with it a more accentuated amount of film grain. This results in a much more cinematic visual experience. This is the best that this movie has ever looked on home video.

In terms of the audio quality, it comes via an Uncompressed Linear PCM 1.0 Mono sound mix. This is the same audio experience found on the previous 2019 Arrow Video Blu-ray. That’s not a bad thing, though. It is just the best that this movie will ever sound on home video. They could have opted for a 5.1 surround mix or Dolby Atmos. However, Arrow Video has chosen (once again) to remain true to the source material. I believe that purists will appreciate that choice and that everyone will enjoy the audio presentation here.

The bonus materials here are essentially all of the Blu-ray content from the 2019 Arrow Video release. They are now ported over to the 4K disc. Since you don’t get a Blu-ray anymore with Arrow Video Blu-ray sets, this is a reality. The movie has to share its space with the extras. I am not a fan of this method of housing supplemental materials. However, it’s a reality, and we have to deal with it. In terms of extras, you get roughly an hour of content, not including an audio commentary.

This 4K UHD Blu-ray Limited Edition release of “The Andromeda Strain” is certainly an improvement. It surpasses all previous home video releases, especially in terms of video quality. It is admittedly comparable in terms of its audio presentation and the extras (on the disc). The 2019 Blu-ray and this new 4K limited edition only differ in a couple of ways. You get a physical booklet and a slipcover with the 4K edition in terms of physical extras. Then there’s the whole 4K resolution and HDR (high dynamic range) thing that goes with video quality. That all being said, this release comes as “a recommended upgrade.”
