''The Cave'' is an Action/Horror movie released in 2005 featuring Creator/ColeHauser and Creator/LenaHeadey.

The story starts 30 years ago when an exploration team excavates an entrance under a Stone church in the Carpathian Mountains, and as they enter in a rockslide traps the explorers under the church, never to be heard from again. 30 years after that, a team of researchers led by Dr. Nicolai and his assistant, Dr. Kathryn begin to explore the area where the exploration team disappeared. Eventually they find access under the church in an underwater river, and a group of experienced divers join the two doctors in exploring further. As they progress along and begin to go deeper and deeper into the earth, Dr. Nicolai learns of the legend regarding the Church, which was built to seal something evil under it, and that Templar Knights would venture into these caves to fight horrid human-like winged demons.

As the research team goes deeper and deeper into the cave, eventually one of the divers is attacked by one of the more carnivorous inhabitants of the cave and causes his breathing apparatus to explode, collapsing the way out of the cave and trapping everybody one mile under, unable to go back and forced to go deeper into the cave in an attempt to get out.

As they go deeper, they discover more of these atrocious winged monsters, and they begin to attack them and killing them off one by one while the team attempts to defy yawning underground chasms, powerful underwater currents, and each other as they begin to learn more sinister things about each other and question whether or not they can trust each other as something begins to develop in their team mates...

At its base, ''The Cave'' was a very good stand alone movie, and while [[DuelingMovies it was released at the same time as a couple other movies with similarities]] (such as ''Film/TheDescent'' and ''Film/TheCavern''), the movie was able to develop a cult following.

!!Tropes that can be found in ''The Cave'':

* ArtisticLicenseChemistry: One character says he can smell methane gas - which is a colourless and odourless substance. Might be not the case. Said character is [[spoiler: already mutated by the parasite, which heightened his senses. And if methane is a common hazard in the cave, the parasite would ''need'' to make its host capable of sensing and avoiding that hazard.]]
* BigBrotherInstinct: Jack for Tyler.
* BlackDudeDiesFirst: Averted. [[spoiler: The Asian is one of the last characters to die and the black guy survives]].
* BunnyEarsLawyer: The caving team are quite quirky but very good. As Jack puts it when they're trapped, the people best qualified to get them out of the cave-in are all currently down there.
* CoversAlwaysLie: No, the team is not attacked by a massive subterranean water monster. While there are monsters and they do travel through water as well, they're human-sized.
* CreepyMonotone: Jack [[spoiler: as the virus starts to spread]].
* DownerEnding: [[spoiler: Everyone except Tyler and Top are dead, while Katheryn is infected and reveals that the creature wanted to escape the cave all along. The last we see of her is disappearing into a crowd of people]].
* DwindlingParty: By the end only [[spoiler: Top, Tyler and Katheryn have survived. And Katheryn is revealed to have the infection]].
* FaceMonsterTurn - One of the explorers, after being attacked by one of the subterranean monsters, begins to start mutating into one of them, his eyes changing into a different shape while also being able to detect the monsters in complete darkness as well.
* FinalGirl: [[spoiler: Looks like it'll be played straight with Katheryn surviving and Charlie dying. But Katheryn has the infection now]].
* FiveTokenBand: We have the two white American brothers, the black guy, the female tomboy, the Canadian and the Australian on the diving team. The expedition also includes the east European doctor, the British female scientist and the Asian camera man.
* HeroicSacrifice: [[spoiler:Jack blows up the last cavern while fighting one of the monsters to give the other survivors an opportunity to escape]].
* HotScientist: Lena Headey as Katheryn of course!
* ImpliedLoveInterest: There appears to be an attraction between Tyler and Katheryn.
* ImprobableAge: Subverted. Katheryn's youth is justified by her being the associate to Dr Nikolai - who is in charge. And Lena Headey was 32 at the time, making her a little more plausible than many other such scientist babes.
* NonActionGuy: Dr Nicolai.
* OhCrap: Charlie when she realises [[spoiler: the creature can fly!]]
* RagtagBunchOfMisfits: The diving team of course. But they've all been together long enough that they're genuinely good at what they do.
* ScaryScorpions: Our cast encounters albino ones in one of the smaller tunnels.
* ShipTease: Between Tyler and Kathryn.
* ShownTheirWork:
** The movie is inspired by true events. Around 35 new species were discovered in Eastern European caves in the 1980s. Romania itself has around 12,000 caves and there is no limit to what could possibly be down there.
** The man laying explosives has VSSF tattooed on his arm. The acronym translates to Swiss Society of Explosive Engineers.
* TentativeLight
* TheVirus: Anyone who is unlucky enough to survive being attacked by the underground flying monsters eventually turns into one of them.
* TwistEnding: [[spoiler: When the team finally escapes from the Cave, it turns out one of the doctors that entered with them is carrying the parasite with them, and vanishes into the crowd of people]].
* TwoGirlsToATeam: Kathryn and Charlie are the only women on the expedition.
* VasquezAlwaysDies: [[spoiler: Two girls on the team - trained cave diver and climber Charlie and research scientist Kathryn.]] Guess which one lives. Though this is semi-justified as [[spoiler: Charlie gets killed precisely because she's a climber; she scales a rockwall before everyone else and gets attacked by a creature]].
* WasOnceAMan: [[spoiler:One of the monsters bears the same tattoo on its hand as one of the cavers previously seen entombed within the cave system at the beginning of the movie. Which bodes poorly for parasite-infected expedition leader Jack]].
