7 Best Alien Sci-Fi Movies to Watch

When citizenship and rights can only be achieved through federal service, you have no choice but to militarize. Johnny Rico is young, impressionable, but noble; in other words, he is an archetypal hero even if he initially enlists just to be close to his girlfriend Carmen (Denise Richards). From then on, Starship Troopers unfolds as a high-strung high school drama, but in the middle of a space colonization. During one such mission, a highly evolved insectoid race, Arachnids, proves to be the most dangerous enemy to human supremacy and the fight is on. What's interesting about Starship Troopers is that it shows how a well-oiled propaganda machine works and for that reason, it was accused of indoctrination and army endorsement. Even more, it was dubbed fascist, instead of the fascist satire it claimed to be. But today, it's indisputably a cult film and a great introduction to the Paul Verhoeven's work in Hollywood.

Animated in every sense of the word, The Mitchells vs. the Machines is a fun and lively watch for anyone of any age. On the surface, it’s about a tech company’s AI going haywire as it turns against humans and takes over the world (an obvious and much-deserved dig at Big Tech). It also immediately stands out as an energetic and inventive film bursting with love for the animation genre.

But at its core, it's about family and learning to love them even and especially when the going gets tough. Teenager Katie and her father Rick are at that precarious moment in their relationship where everything they do seems to annoy the other, while Katie's mother Linda tries and fails and tries again to keep the peace. The Mitchells are filled with love, but they’re not quite sure how to express it to each other, and it's both funny and relatable how it takes a literal apocalypse for them to realize that. This is a family story elevated by dynamic animation and a bizarro storyline. Expect it to go off the rails in the best possible way.

Part sci-fi and part psychological horror, No One Will Save You is an impressive outing that serves as a vehicle for Dever’s one-woman show. She is a powerhouse, a nonstop show of talent that doesn’t seem to run out of fuel. The scenes are grueling and excruciating, they involve a lot of physical, mental, and emotional turmoil, but somehow, Dever rises to the challenge with unbelievable ease. Sure, sci-fi lovers will find much to discuss in these unearthly creatures, and cinephiles will appreciate how the film relies almost solely on sound design and a single line of dialogue. But it’s Dever who does the heavy lifting here, and it’s especially apparent when the film tries, weakly, to delve into Brynn’s psyche and the town’s sociological workings. It’s not as impressive in those regards, but Dever is strong enough an actress to make you forgive the movie’s frailer parts.

Galaxy Quest may be a parody of the sci-fi franchise, but it’s also a huge fan of it. It forgoes cynical takes for smart odes to the genre, all while retaining an endearing sense of humor about it. It’s silly and self-aware, and it has a lot of fun letting us know that they’re in on the joke. You can watch for the interesting premise, but you'll stay for the laughs and the promise of a genuine thrill ride. Everyone is a blast to watch, but Sigourney Weaver and Sam Rockwell deserve special praise for being outright hilarious, elevating Galaxy Quest from B-movie to camp classic status.
