When we last saw Sophie Thatcher, she worked in 2024’s psychological thriller Heretic. 2025 brings her back to horror with Companion.

Joined in a still fresh relationship, Josh (Jack Quaid) and Iris (Thatcher) take a weekend trek to a lakeside estate owned by the mysterious Sergey (Rupert Friend). Along with Sergey’s mistress Kat (Megan Suri), another couple that consists of Patrick (Lukas Gage) and Eli (Harvey Guillén) visit as well.

After some fun and frivolity, things go down a dark path when Sergey tries to rape Iris and she kills him. This leads to shocking revelations that turn the entire group upside down.

The big “shocking revelation” will seem less shocking to those who saw the film’s trailer. In an ad that revealed too much, the promos for Companion gave away its big twist.

In the defense of the folks who created those reels, the movie brings out this information fairly early in the story. It also offers some hints that something’s up along the way.

Still, it seems like a shame that so many first-time viewers of Companion won’t get to encounter the surprise in real-time. At least the folks who put together this disc’s box art kept things mum, as the back cover blurb reveals literally nothing.

Even with foreknowledge of the twist, Companion works well. While it might become more fun without prior awareness, the film takes so many delicious twists and turns that it doesn’t need the element of surprise to succeed.

Of course, all of this makes it really tough to discuss Companion without spoilers. So much of the tale connects to the character curveballs that this limits my ability to dig into the flick.

Suffice it to say that Companion doesn’t act as a one-trick pony that loses steam once the “revelation” unveils. Indeed, it holds up as well on second viewing as it does the first time.

That happens because the movie comes with so many twists unrelated to the primary character reveal. Even after that point, Companion throws out lots of unpredictable moments that constantly delight.

None of these seem gratuitous. Even as wild as the flick becomes, it fits into a consistent framework and doesn’t go crazy just for cheap effect.

An excellent cast grounds Companion as well, with special note needed for Thatcher’s stunning lead performance. Iris goes through massive changes as the story proceeds, and Thatcher handles all of them with aplomb.

Without Thatcher, I suspect Companion fares substantially less well. She holds together the flick at its core and really delivers the goods.

Honestly, I find nothing about which I can complain when it comes to Companion. It uses the horror/thriller format in creative ways and becomes a blast from beginning to end.

Companion appears in an aspect ratio of 2.35:1 on this 4K UHD Disc. This became a pretty solid image.

Overall sharpness worked fine, with only some light softness in a few interiors. These didn’t become an issue, though, as the majority of the flick boasted solid delineation.

No concerns with jagged edges or moiré effects occurred, and I saw no edge haloes. Source flaws failed to become an issue.

The movie’s palette tended toward a low-key set of tones with subdued greens, pinks, and ambers mainly. These came across as intended, with a bit of a boost from HDR.

Blacks felt deep and dark, while shadows brought positive clarity. HDR added punch to whites and contrast. I felt happy with this pleasing presentation.

Downconverted to Dolby TrueHD 7.1, the movie’s Dolby Atmos mix worked fine for the story at hand. This meant it didn’t dazzle but it fleshed out the spectrum in a satisfying manner.

A few violent moments offered the most engaging material, but those didn’t pop up with great frequency. Much of the flick opted for environmental information as well as music, all of which filled the soundscape in a rich way.

Audio quality pleased, with speech that appeared natural and concise. Music felt full and dynamic.

Effects came across as accurate and vivid, with solid low-end. While not the most ambitious track, the mix suited the story.

Three featurettes flesh out the disc, and I Feel, Therefore I Am runs five minutes, 43 seconds. It involves writer/director Drew Hancock, producers Zach Gregger and Raphael Margules, executive producers Tracy Rosenblum and Jamie Buckner, and actors Sophie Thatcher, Jack Quaid and Lukas Gage.

“Feel” examines story/characters as well as cast and performances. A few insights emerge but it mostly comes across as insubstantial.

Love, Eli lasts four minutes, 26 seconds. It offers info from Gage, Hancock, Quaid and actors Megan Suri and Harvey Guillén.

Like the prior reel, “Eli” gives us more story/character and cast/performance domains. It also seems superficial for the most part.

Finally, AI Horror goes for five minutes, nine seconds. This one delivers comments from Quaid, Thatcher, Hancock, Buckner, Gregger, costume designer Vanessa Porter and visual effects supervisor Jamison Goei.

“Horror” discusses the futuristic tech elements of the movie and some facets of Iris’s character. It seems a bit more interesting than the other two but not by a lot.

With a lot of delightful twists and a stellar lead performance from Sophie Thatcher, Companion turns into a vivid experience. It gives its own spin on a particular form of horror/thriller and keeps the viewer involved the whole way. The 4K UHD offers positive picture and audio but supplements seem too insubstantial. I wish we got better bonus materials but I still recommend this terrific movie.
