Physical media collectors are a picky bunch. We want the best bitrates, the punchiest HDR, and—most importantly for the Ridley Scott and Fede Álvarez fans out there—we want every single pixel captured by the camera. That is why the conversation around the Alien Romulus IMAX version Blu-ray has become such a heated topic in home theater forums lately. People don't just want the movie; they want the 1.90:1 expanded aspect ratio that filled screens in IMAX theaters back in August 2024.
Let's be real for a second.
Most Blu-rays give you the "letterboxed" experience. You get those black bars at the top and bottom of your TV because the movie is presented in a wide 2.39:1 aspect ratio. But Fede Álvarez shot Alien: Romulus using the Arri Alexa 35, a beast of a camera that captures a taller image. In IMAX theaters, the movie opened up. It felt more claustrophobic and more massive all at once. If you've ever seen Interstellar or The Dark Knight on disc, you know how those sequences suddenly fill your entire 16:9 television. It's a game-changer. So, where is that version for Romulus?
The Frustrating Reality of the Home Release
The standard 4K UHD and Blu-ray releases of Alien: Romulus hit shelves with a fixed 2.39:1 aspect ratio. Honestly, it’s a bit of a letdown for those of us who spent the extra fifteen bucks at the cinema to see the taller frame. Disney and 20th Century Studios have a weird history with this. Look at the Marvel Cinematic Universe. If you want the IMAX Enhanced versions of those movies, you usually have to stream them on Disney+. The physical discs? They stay letterboxed.
This creates a weird rift in the collecting community.
You’ve got guys like Bill Hunt over at The Digital Bits who have been beating the drum for years about "IMAX on Disc." The technical argument is simple: why leave image data on the cutting room floor? When you're watching the Alien Romulus IMAX version Blu-ray—or rather, the version we hope eventually exists—you’re getting roughly 26% more picture. In a franchise defined by facehuggers leaping from the shadows, that extra vertical space at the top and bottom of the frame adds a lot of genuine tension.

Why Disney Keeps the IMAX Version Locked Away
It's mostly about licensing and "platform stickiness." Disney wants a reason for you to keep paying for Disney+. By offering the IMAX Enhanced version exclusively on their streaming service, they create a value proposition that a "dead" format like a disc supposedly can't match. But we know better. A 4K disc has a bitrate that laughs at streaming. Streaming a 4K movie usually tops out at 15-25 Mbps. A physical 4K disc can soar past 100 Mbps.
Shadow detail matters in an Alien movie.
If you’re watching the scene where Rain and Andy are navigating the Corbelan through the debris field, the compression artifacts on a stream can turn those beautiful deep blacks into a blocky, grey mess. This is why the demand for a dedicated Alien Romulus IMAX version Blu-ray is so high. Collectors want the tall image and the high bitrate.
Technical Specs: What We Actually Got vs. What We Wanted
The current 4K release is still a technical powerhouse, don't get me wrong. It features a native 4K DI (Digital Intermediate) and a Dolby Atmos track that will absolutely rattle your floorboards. The HDR10 grade is sharp. It’s gritty. It looks like a classic 1979 sci-fi flick but with modern clarity.
But it’s missing that "wow" factor of the variable aspect ratio.

- Format: 4K Ultra HD / Blu-ray
- Aspect Ratio: 2.39:1 (Standard Widescreen)
- Audio: Dolby Atmos (4K) / DTS-HD Master Audio 7.1 (Blu-ray)
- HDR: HDR10 (No Dolby Vision on the standard disc, which is another gripe)
If you compare this to something like the Top Gun: Maverick or Oppenheimer discs, the difference is glaring. Christopher Nolan insists that his IMAX sequences are preserved on the Blu-ray. He understands that the home theater enthusiast is his core audience. For some reason, the team behind the Alien home releases hasn't quite caught up to that philosophy yet.
Is a "Special Edition" IMAX Release Likely?
Hope isn't entirely lost. We've seen "double dipping" happen plenty of times in the past. Remember Avatar: The Way of Water? It had a standard release and then a massive Collector's Edition months later.
There is a very real possibility that 20th Century Studios is waiting for a "Complete Collection" or a "Director’s Cut" to drop the Alien Romulus IMAX version Blu-ray. Fede Álvarez is a huge fan of the franchise and very active on social media. He knows the fans want this. Often, these decisions are made by suits in a boardroom who are looking at quarterly earnings rather than artistic intent, but fan pressure does work.
James Cameron eventually gave in on the Abyss and True Lies 4K releases (even if the AI upscaling on those was... controversial, to say the least). If enough people hold off or keep asking for the IMAX ratio, a boutique label like Criterion or even a premium Disney "Legacy" release could happen in late 2025 or 2026.
The "IMAX Enhanced" Streaming Alternative
Right now, if you want to see the expanded ratio at home, your only real legal path is waiting for the IMAX Enhanced tag to appear on Disney+. It’s not a Blu-ray, but it’s something.

The irony? Most people watching on a phone or a laptop won't even notice the difference. But if you have an 85-inch Sony or a projector setup, that extra height is the difference between "watching a movie" and "being in the movie." It changes the scale of the Renaissance Station. It makes the "Offspring" creature at the end of the film feel even more hulking and unnatural because its head and feet aren't being cut off by the cinematic bars.
How to Optimize Your Current Viewing Experience
Since we are currently stuck with the 2.39:1 version on the physical Alien Romulus IMAX version Blu-ray (or lack thereof), you have to make the most of what’s on the disc.
First off, turn off any "motion smoothing" or "soap opera effect" on your TV. Alien: Romulus was shot to look like it belongs in the late 70s. It has a specific texture and grain.
Secondly, if you’re a real nerd about this, look into "constant image height" (CIH) setups. Some high-end users use an anamorphic lens on their projectors to fill a wide screen, though that doesn't actually solve the "missing" IMAX data. It just makes the 2.39:1 image look massive.
Actionable Steps for the Serious Collector
- Check the Labels: Before buying, ensure you aren't accidentally buying a region-locked import. Most 4K discs are region-free, but the standard Blu-rays included in the pack often are not.
- Monitor Boutique Announcements: Keep an eye on companies like Manta Lab or WeET. They often do premium "Full Slip" or "Lenticular" releases of big blockbusters. While they usually use the same discs as the retail version, they sometimes negotiate for different masters or at least provide the best possible packaging for the existing Alien Romulus IMAX version Blu-ray content.
- Sign Petitions and Tag Directors: It sounds silly, but Fede Álvarez actually listens to fans on X (formerly Twitter). Direct engagement about the IMAX ratio helps show Disney that there is a market for a "Special Edition" disc.
- Wait for the Steelbook Restocks: The Alien: Romulus 4K Steelbook sold out almost instantly. If you're going to buy the "wrong" aspect ratio anyway, you might as well get the one that holds its resale value.
The dream of a definitive Alien Romulus IMAX version Blu-ray remains just that for now—a dream. We have the movie, and it’s a great movie, but we’re only seeing part of the picture. Until the studios realize that physical media buyers are the ones who care most about "Director's Intent," we'll keep having those black bars. For now, the best move is to buy the 4K for the audio and bit depth, but keep your ears to the ground for a 2026 "Anniversary" or "Special Edition" that finally opens up the frame.
