In this incredibly cool sci-fi drama, two science geek best friends, C.J. and Sebastian, work together to create a time machine that will allow them to save C.J.'s brother, who was wrongfully killed by a police officer. Time travel hasn't been this cool since Michael J. Fox did it in Back to the Future.

In perhaps the sexiest sci-fi film ever made, Tomb Raider star Alicia Vikander and Crazy Rich Asians actress, model, and ballerina Sonoya Mizuno play two female humanoid robots desperate to experience the outside world, even if that means killing their creator. Think Westworld, but even wilder.

Watch Ex Machina on Netflix.

Though Scarlett Johansson never actually appears in this film, she still manages to woo us (and Joaquin Phoenix) as the sexy voice of Samantha, a new operating system with a sensitive, playful personality. We'd like to see Siri try to do that.

Watch Her on Netflix.

With a cast that includes Sandra Bullock, Sarah Paulson, and John Malkovich, this post-apocalyptic horror film follows a woman and her children in their attempt to find sanctuary after a mysterious force decimates most of the population.

Watch Bird Box on Netflix.

Starring Kiernan Shipka and Stanley Tucci, this horror film tells the story of a deaf teen named Ally who moves with her family to escape terrifying creatures who hunt humans by sound. In their remote new town, they instead face a new threat: a cult that wants to exploit Ally's heightened senses.

Watch The Silence on Netflix.

Scarlett Johansson stars in this movie about a predatory alien disguised as a beautiful woman who tries to lure unsuspecting male victims into her van. To be honest, we're not sure we'd be able to resist the temptation of Johansson either.

Watch Under the Skin on Netflix.

If you want to see the film that launched filmmaker James Cameron's career (and solidified Arnold Schwarzenegger as one of the greats), then you'll want to watch this sci-fi classic, which eventually led to an insanely popular franchise with four sequels. Schwarzenegger plays a cyborg assassin sent from 2029 back to 1984 to kill Sarah Conner before she can give birth to a future resistance leader, and it's a must-see if you want to know where everyone's fear of an AI takeover (and the catchphrase "I'll be back") originated.

Watch The Terminator on Netflix.

Basically every kid growing up in the '80s (and probably every adult, too) was given nightmares by this horror flick about cute little pets called mogwais that — when exposed to light, water, or food after midnight — turn into hell-raising beasts called Gremlins. And you thought your possessed Furby was scary.

What is the Matrix, you ask? Neo (Keanu Reeves) believes that only the elusive figure known as Morpheus (Laurence Fishburne) can answer that question, and when a beautiful stranger named Trinity (Carrie-Anne Moss) leads him into an underworld to meet Morpheus, he tries to get the answer he seeks, not knowing that the truth could cost him his life — or something even more valuable. Even if this one leaves you feeling more confused than 2010's Inception, it's still a total thrill to watch.

As you can probably gather from the title, this monster comedy revolves around the SUV-sized spiders — created as the result of a chemical spill — and the people forced to take them down (including David Arquette and Scarlett Johansson). Gross? Yes, but still way funnier than you'd expect.

Watch Eight Legged Freaks on Netflix.

Bradley Cooper stars in this underrated movie as a down-on-his-luck writer named Eddie who — when given a drug that enhances mental acuity — finds himself rising through the ranks in the world of finance. Though a major tycoon (played by Robert De Niro) hopes to use the young man for his own gain, Eddie's dwindling drug supply spells big trouble for them both.

Watch Limitless on Netflix.

The flap of a butterfly's wing in Brazil sets off a tornado in Texas. The ability of Ashton Kutcher's character in this movie to travel back in time to tragic moments (both in his life and in friends' lives) and then try to change those moments sets off a nightmarish chain of events.

Watch The Butterfly Effect on Netflix.

In this sci-fi romance, Jason Segel stars as Will, the son of a famous scientist who — due to a scientific breakthrough — has found definitive proof of an afterlife, which then leads to a huge spike in suicides.
