Edge Of Tomorrow Trailer

16. District 9 (2009)

District 9 Official Trailer

For nearly 30 years, a behemoth UFO has floated, dormant, above the South African city of Johannesburg. It’s occupants; a trapped population of incredibly intelligent alien beings—derogatorily nicknamed ‘prawns’—who have had no choice but to accept residence in segregated slums. Their ship is broken—unable to carry them home—and xenophobic humans want nothing more than to see them leave, or be wiped out. But when ignorant MNU employee Wikus van de Merwe tries to relocate the prawns to District 10, he is forced to relate to them on a level no other human possibly could...  

The horrific realities of the racially-oppressive ’Apartheid’ are paralleled in District 9, serving as a humbling reminder of humanity’s ugliest traits—alongside insanely visceral action.

Unfortunately for them, they aren’t alone after all.

An inhuman threat lurks not only around the surviving colonists, but also within them...

14. Sector 7 (2011) [Korean]

Isolated on an oil rig in stormy seas, the crew must survive against a terrifying creature of unknown origin.

13. Beyond Skyline (2017)

Venom Official Trailer

Enter one of the MARVEL universe’s most-loved anti-heroes. Eddie Brock, an investigative journalist looking into nasty rumors of human-experimentation by the Life Foundation corp.

Tom Hardy stars as the man consumed by this malicious entity. Pretty smile though...

11. Life (2017)

Life Official Trailer

With a ‘safely’ isolated place to study it, it becomes clear that it is unlike anything known to man. Unfortunately for the station’s crew, the rapidly growing organism isn’t too keen on being examined—and what began as history’s greatest scientific discovery quickly turns into its deadliest.

It turns out there was life on Mars after all. Maybe we should have left it there...

10. Aliens In The Attic (2009)

Aliens In The Attic Trailer

When the Pearsons discover a scouting party of little green aliens in the attic of their summer home, the goal of the season shifts to ‘protecting the Earth from invasion’—instead of... whatever a family of teens typically get up to at a summer house. But there is one alien among them who isn’t so enthusiastic about the whole ‘invasion thing,’ and may just be willing to change teams...

The fate of the planet hangs in the balance—but that doesn’t mean you can’t have a good laugh while saving it.

9. Pacific Rim (2013)

Pacific Rim Official Main Trailer

An unfathomable threat has emerged from the depths of our planet. Gargantuan monsters are storming the shores of human civilization to terrorize and wreak havoc. Our answer against these mountain-sized abominations? Fight size with size. Enter the Jaegers: giant mechs operated by two highly specialized pilots each, wielding immense firepower and strength.

Inspired by the Japanese ’Kaiju’ genre, in which massive monsters terrorize society (ie, Godzilla).

8. Battle: Los Angeles (2011)

Battle: Los Angeles Official Trailer

Retirement gets put on-hold for U.S. Marine Michael Nantz when the skies over Los Angeles start raining UFOs. Emerging from the fallen pods are aliens hell-bent on war, forcing all able-bodied soldiers into battle on their very own home-front.

Initially thought to be a cluster of meteorites, the plummeting objects turn out to be containing creatures with little interest in diplomacy.

7. Starship Troopers (1997)

Starship Troopers Trailer

A race of insectoid aliens threatens everything that humanity stands for! When the war against the ‘bugs’ hits too close to home, Johnny Rico commits himself fully to the Mobile Infantry and finds himself on the distant planet Klendathu, face-to-face with the creatures themselves. Maybe exposure to the horrors of combat will allow him and his friends to reflect on just exactly who is invading whom?

The movie is loosely based on Robert A. Heinlein’s 1959 novel of the same name.

6. The Thing (1982)

The Thing Official Trailer

In Antarctica, scientists discovered something preserved deep beneath the polar ice. Something not of this world... When the organism is thawed out and makes its way to a neighboring research station, all hell breaks loose. This thing can alter its form, inhabiting the bodies and personalities of its victims. A new level of paranoia sets in as distrust grows between the station’s dwindling inhabitants. Who could it be?...

John Carpenter’s 1982 remake is particularly renowned for its ground-breaking, gruesome practical effects.

5. The Thing (2011)

The Thing Official Trailer

A prequel to the aforementioned 1982 film (of the same name), this Thing follows the original Norwegian research team that discovered the entity. At first unearthing a massive ship of sorts beneath the ice, they happen upon its ‘pilot’ nearby (also frozen). It is clearly a remarkable discovery, but its form and biological structure have the scientists perplexed. Unfortunately for them, the thawing of the specimen’s icy cage means they soon get to experience its capabilities first-hand.

This story ties directly into the very beginning of John Carpenter’s original, answering some questions while raising others.

4. War Of The Worlds (2005)

War Of The Worlds Trailer

Witness the ultimate alien invasion. When towering tripods appear and start disintegrating and abducting people, Ray Ferrier has to do whatever it takes to keep himself and his two children alive. In the blink of an eye, everyday American life is transformed into a hellish battlefield with too few places to hide. No one knows why these beings are waging this unprovoked war, but nothing is without a weakness—it’s just finding it while staying alive that’s the problem.

Steven Spielberg’s 2005 film is one of many adaptations of H.G. Wells’ 1898 novel ’The War of the Worlds’—considered one of the most influential sci-fi stories of all time.

3. Predator (1987)

Predator 'Throwback' Trailer

Dropped into the jungles of Central America, what begins as a relatively routine hostage-rescuing operation, for 7 elite commandos, quickly turns into a deadly confrontation with an unseen foe that only just arrived on our planet. As skinned corpses and skeletal trophies soon make it clear that this thing is hunting for sport, Dutch’s unit of bad-asses have no choice but to hurl everything they’ve got at this jungle stalker. Yes, it can see in thermal vision. Yes, it has active camouflage. Yes, it has crazy high-tech weaponry.

But ya know what it doesn’t have?... Dutch’s muscle-bound brain.

It had already been established that Arnie could demolish any human specimen, but what about alien specimens?...

2. Predators (2010)

Predators Official Trailer

When 8 people regain consciousness falling through the sky with parachutes on their backs, the possibility that they were no longer on Earth had not yet occurred to them. Realizing that they are each ‘killers’ in their own ways—whether a black ops commando, a cartel enforcer, or a murderer on death row etc.—it’s not long before they understand that they were selected for a singular purpose: to be hunted.

Stranded on a game-preserve planet by an alien race of sport-hunters, these humans will have to embrace their own violent nature as predators.

Intended as a rebooted direct sequel to the original, the title ’Predators’ refers both to the aliens and the humans themselves.

1. ALIENS (1986)

ALIENS "It's War" Trailer

“They mostly come at night... Mostly...”

Following the horrific events of the original, Lt. Ellen Ripley finds herself face-to-dome once more with the creature that haunts her dreams—only this time each side has a few more friends. Hoping that her knowledge of the beast can help save the colonists of LV-426, she accompanies a platoon of well-armed Colonial Marines back to where it all began.

Not long after arrival, it becomes brutally clear that not only were they too late for the colonists, but extreme firepower—it turns out—won’t be enough to guarantee anyone’s safety. As their numbers rapidly dwindle, so too do their hopes of ever leaving this nightmare. But Ripley’s come too far to go down without a fight.

ALIENS, while maintaining a lot of the original’s central horror theme, opted for a more action-oriented approach through the introduction of gun-toting marines and WAY more aliens to kill.

And that's 25 for ya...

Although Yoda-knows there are many more titles that belong here, hopefully you’ve been able to find a number of suggestions for getting that much-needed alien fix. While the tone in these movies varies from the more humorous and light-hearted to the straight-up horrifying and nightmare-inducing, it pretty well represents our limitless imagination when thinking about what else might be out there in the cosmos. Whether or not we really want to find out is the million-dollar question...
