10 More Great Sci-Fi Horror Movies (No One Ever Talks About)

From extra-terrestrials invading the planet to time-travel paradoxes, sci-fi horror has always maintained a captivating allure for movie enthusiasts. Although Alien, The Fly, and Predator were instant hits and left their mark on the genre with immediate effect, there are plenty of solid sci-fi features that took considerably longer to take off.

In recent years, formally unappreciated films like Event Horizon, They Live, and The Mist have found a new level of popularity. They may have done badly with critics or the box-office at launch, but have since elevated themselves to cult-classic status.

Although it's reassuring for gems like these to eventually find their audience, there are many other great sci-fi flicks that nobody seems to talks about. Even though some entries on this list may be known to die-hards it still feels like these films still don't get enough credit.

Since cinephiles are always on the hunt for something new, they'll be happy to know there is an abundance of obscure space thrillers, Lovecraftian-inspired features, and twisted mind-benders yearning to be discovered. In a few years, let's hope these sci-fi horrors finally receive the recognition they rightfully deserve.

Underwater begins with a deep-sea facility being struck by a cataclysmic earthquake. As water bursts in through every seam, marine engineer Norah (Kristen Stewart) sprints through the flooding corridors, looking for a way out. After watching this heart-pounding and magnificently choreographed sequence, viewers should be on the edge of their seat.

And that's only the first five minutes. Once the aquatic life start attacking the survivors, things become far more nerve-racking.

The entire cast is exemplary, but Kristen Stewart is the one who shines brightest. Using subtle facial expressions, she's easily able to convey a mix of strength and vulnerability. You can see the wheels turning in her head in each scene, as she attempts to find solutions to her party's mounting problems.

Even though the sea critters are dangerous, Underwater emphasises a more imposing threat that few sci-fi films acknowledge: pressure.

Since the crew are in the Mariana Trench, they must contend with the crushing weight of the ocean. If a diver's suit or a room isn't depressurised correctly, the team can implode in an instant. (Some characters learn this the hard way.)

Although science-fiction usually ignores the "science" part, acknowledging the dangers of pressure adds a gargantuan obstacle to the group, compounding the tension.
