Sci-fi and horror have long gone hand in hand. Science fiction is a genre that deals with the future and the uncertainty the human race and the planet face while horror aims to tap into our most primal fears. Naturally, when the two genres meet on screen the product can be terrifying. TheAlienfranchise became one of the highest-grossing franchises of all time, permeating pop culture and influencing many movies that came after it.
What about the films that don’t make the splash thatmovies likeAliendid? With so many releases each year, from theatrical blockbusters to straight-to-home videos, it’s easy for some to get overlooked.

Pandorum
Released in 2009,Pandorumflopped at the box office. The plot is somewhat typical of many sci-fi films, with the Earth depleted of natural resources, a kind of space ark is built, housing 60,000 humans on a mission to colonize a far-off planet. The journey is set to take over 100 years and to man the ark they have a rotating crew,who come out of stasisto take their turn helming the ship. When Lieutenant Payton (Dennis Quaid) and Corporal Bower (Ben Foster) wake up to take their shift something goes wrong and they emerge with partial amnesia and find the ship experiencing periodic power surges due to a faulty reactor.
WherePandorumstands out is in the twists and turns in the plot, the inclusion of space mutants, and the outstanding performances from the two main leads. The film is a claustrophobic and grislycommentary on human natureand mental illness with interesting set designs and tense sequences that has started to find a wider audience in recent years.

Annihilation
Based on the 2014 novel of the same name,Annihilationstars Natalie Portmanas an army veteran and cellular biology professor Lena who has been investigating a phenomenon known as The Shimmer. The Shimmer is a strange zone that materialized at the site of a meteorite crash where all plant and animal life inside is mutating. One year after her husband disappears during a mission into The Shimmer, he re-appears at their home and quickly begins to deteriorate. This leads to government intervention and Lena agreeing to investigate The Shimmer.
Upon its release,Annihilationdid poorly at the box office. However, it is a film deserving of a second chance. The special effects are beautiful and frightening in equal measure, with an interesting premise and creepy creature and plant designs. The movie explores difficult ideas and themes and leaves a lot unanswered or open-ended for the audience to decide.

The Void
Directed by Steven Kostanski,The Voidis a Lovecraftian horrorthat features incredible practical effects. Set in a small-town hospital, The Void follows a group of people trapped inside a hospital by cultists that are surrounding the building and attempting to kill anyone that leaves. The only problem is that what is already inside the hospital may be much, much worse than the threat outside. Inside the hospital, people are changing and twisting, physically and mentally as the barriers between worlds begin to break down.
All of the practical effects werecrowdfunded on Indiegogoand the movie was received positively upon its release. With an 80s feel, heavy gore, and pretty extreme body horror,The Voidharks back to early video nasties but also brings them up to date and makes it seem fresh.

The Hidden
Starring Kyle MacLachlan as a strange FBI agent, a departure from his role inTwin Peaksas a strange FBI agent, hunting a murderer across the country. The difference with this case is that the murderer is a body-hopping slug-like alien and that Kyle MacLachlan’s character Gallagher is also an alien, albeit an alien police officer who has traveled across the galaxy toapprehend a thrill-killing aliencriminal. The movie itself features a lot of action sequences and some dark humor elements that overall make an interesting and thrilling cinematic experience.
Largely unseen today,The Hiddensits in a strange in-between realm of genres with sci-fi, horror, action, and comedy rolled into one but each element works together to create a cohesive and fun film led by great performances that is deserving of a wider audience.
