ADDITION: Paramount 4K UHD (August 2022): Paramount are releasing Paul W.S. Anderson's "Event Horizon" to a steelbook-cased 4K UHD. There is a lot to say here. Firstly the package includes a second disc Blu-ray. It is the exact same one that Paramount released in 2008 (reviewed HERE), as evidenced by the file dates:

NOTE: In 2021 there was a Shout! Factory Blu-ray released of "Event Horizon" with a 4K restoration, HERE, but we don't own it to compare.

There are two major factors at play here. Firstly the obvious vertical stretching (thinner faces) of the 2008 Blu-ray (yes, the same Blu-ray included in this Paramount 4K UHD) which are more apparent in direct comparison. But 'Carl' did tell us in 2008 (from our review):

NOTE: Carl in email tells us: "This release is still vertically stretched. Maybe on encoding the original 1080p master for the last special edition they just scaled vertically to fit 1.85:1 into 1.78:1, but maybe there is another explanation.

You can tell its stretched in the corridor shot and the screen graphics which should be circular, but look like horizontally narrow ovals instead.
The stretching was not there in the original DVD releases nor in the European DVD releases.

It seems to have occurred when making the last US DVD special edition where this stretching was first appeared. Now the stretching seems to have carried over to the USA blu-ray release.' (Thanks Carl!)

Well, with direct comparison with the HDR-utilized 4K UHD we can see how much it is stretched. It's a lot - an error that was never rectified and remains in this 1080P 14 years later.

The second factor is also significant and is in regards to the 2160P 4K UHD transfer. Event Horizon was shot with the Panavision Panaflex Platinum... in 35mm. Where is the grain? It appears to have been removed and the resulting image is waxy morass, losing definition to the stretched BD. Strangely the extensive, if dated, effects are eye-candy that distract from the soft facial close-ups. It's not that it looked horrible on my system - the grandiose effects helped the overall - but it is not particularly impressive or film-like 4K image with the grain removal.    

It is likely that the monitor you are seeing this review is not an HDR-compatible display (High Dynamic Range) or Dolby Vision, where each pixel can be assigned with a wider and notably granular range of color and light. Our capture software if simulating the HDR (in a uniform manner) for standard monitors. This should make it easier for us to review more 4K UHD titles in the future and give you a decent idea of its attributes on your system. So our captures may not support the exact same colors (coolness of skin tones, brighter or darker hues etc.) as the 4K system at your home. But the framing, detail, grain texture support etc. are, generally, not effected by this simulation representation.

NOTE: 50 more more full resolution (3840 X 2160) 4K UHD captures, in lossless PNG format, for Patrons are available HERE

On their 4K UHD, Paramount use a similar TrueHD (sole English-language option), 5.1 surround track, also offering (with a handful of foreign-language DUBS and subtitle options) although it is far more robust than the 2008 Blu-ray (5464 kbps to the BD's 3452.) It's pretty intense - laced with effects and jumping bass and the TrueHD is up to the challenge with vast separations spreading the breadth of your surround channels. I'd venture to say the aggressive track is more viable than the image. This will surely rock your floorboards and windows with dynamic bass response - thanks to the film! The, occasionally intense, score is by Michael Kamen (The Dead Zone, Venom, Mona Lisa, Polyester, Road House, Company Business) with collaboration from the electronic dance music duo Orbital providing synthesized, unsettling, sounds. The result is an energetic, if not especially memorable, track for Event Horizon that is filled with bombastic, piercing, effects. They can punctuate scenes with dominance - a huge, actually overwhelming, part of the viewing experience. The disc offers optional subtitles (sample below) - and is, like all 4K UHD, region FREE, playable worldwide.  

There are zero extras on the 4K UHD disc - they didn't even port over the commentary. But the second disc 2008 Blu-ray, is here with supplements all taken from the last 2-disc SCE DVD (all in SD too.) No one can fault director Anderson for not giving his time to these extras - with a full commentary and optional ones on a couple of the deleted scenes etc. Anderson and Producer Bolt soldiered through it with plenty of production details. Somewhat exhausting is the 5-part Making of... feature which actually has a longer running time than the film itself. You have the evolution of the film and much more on production and effects. We certainly don't want to look a gift-horse in the mouth and for those keen enough on the film - the extras are available to indulge (conveniently on the one disc with the feature sporting a high bitrate). I will admit seeing them did marginally increase my appreciation of the film - a massive amount of work went into the creation of Event Horizon. There is also a trailer in HD! The package has a handsome Steelbook case in a plastic transparent sleeve - and there is a digital download leaflet with code.

Paramount's release of Paul W.S. Anderson's "Event Horizon" to a Steelbook-cased 4K UHD has some issues, I'm afraid. Let's talk about the film; firstly, What is an "Event Horizon"? In astrophysics, the term was coined by Wolfgang Rindler in the 1950s. It's a boundary beyond which events cannot affect an observer. Anderson's film starts as a fairly intelligent science-fiction horror stacked with effects - gore and deep space technos in darkness with beams of filtered light. "Event Horizon was a commercial and critical failure but has developed a cult following in recent years. It states on Wikipedia HERE, that "He (Anderson) incorporated significant influences of moderately successful horror films such as Robert Wise's The Haunting (1963) and Kubrick's The Shining (1980), because they created suspense from the unknown—the evil presence was hidden from the viewer—and their endings induced ambiguities of perception in the audience." Many scenes in "Event Horizon" are well realized and it has some striking horror imagery with intense sound effects but we can neither endorse the film (although I have gained minor appreciation) nor these Paramount digital versions - except to the less-discerning home theater owner - who is a devout fan of Anderson's film. To each his own.
