He has been writing professionally about pop culture for eight years. Luc's areas of interest are broad: he's just as passionate about psychology and history as he is about movies and TV. He's especially drawn to the places where these topics overlap. Luc is also an avid producer of video essays and looks forward to expanding his writing career. When not writing, he can be found hiking, playing Dungeons & Dragons, hanging out with his cats, and doing deep dives on whatever topic happens to have captured his interest that week.

Hollywood has given the world most of the genre's greatest masterpieces , from the classical grandeur of 2001 to the mythic adventure of Star Wars . With that in mind, this list attempts to rank the very best American sci-fi movies ever.

With The Fly , David Cronenberg gleefully mashes together 1950s-inspired pulp sci-fi, visceral body horror , and dark comedy, all with a more crowd-pleasing treatment than his work usually offers. Jeff Goldblum turns in one of his very best performances here as Seth Brundle, an eccentric scientist who invents a revolutionary teleportation device.

One of the darkest sci-fi movies of the '80s, The Thing follows a team of researchers stationed at an isolated Antarctic outpost who encounter a shape-shifting alien capable of perfectly imitating any living organism. As the creature infiltrates the group, trust begins collapsing and every human interaction becomes a potential threat. Uncertainty itself threatens to tear the group apart.
As with The Fly , the practical effects are truly legendary. Decades later, the creature transformations, handled by icon Rob Bottin , still feel shocking, imaginative, and deeply disturbing. Yet the movie's lasting power comes less from the gore than from its psychological tension. The mood is one of ever-increasing dread, turning an alien invasion premise into a study of fear and distrust . The famousl…
