The genre of science fiction is one that both captivates and puzzles audiences worldwide, and that often starts conversations about topics both real and abstract. From AI to aliens, from spaceships and time travel to robots, there are countless stories and ideas to explore in sci-fi movies. Here is a list of 12 must-watch cult sci-fi classics that will undoubtedly entertain, excite, and challenge viewers: Blade Runner, The Matrix, Star Trek, Ex Machina, E.T. the Extra-Terrestrial, The Terminator, Doctor Who, The Fifth Element, Aliens, The Day the Earth Stood Still, A Space Odyssey and Avatar.

Time Travel

Time travel is the concept of traversing through time and is a common theme in science fiction movies. Some cult classics that feature time travel, and utilize it cleverly, are The Terminator, Doctor Who and The Fifth Element. The Terminator series follows the tale of a resistance attempting to prevent the Skynet Defense System from taking over and destroying the world, while Doctor Who follows the adventures of a time-travelling humanoid alien as he navigates through life. Lastly, The Fifth Element has a protagonist seeking out four ancient stones in order to restore peace to the universe.

By traveling through different timeframes, these movies enable viewers to experience the past, present, and future in ways that are both educational and entertaining. Through unique time-jumps, viewers can be challenged to think differently and more critically about the nature of time and reality.

Artificial Intelligence

Artificial intelligence (AI) is also a popular and essential part of sci-fi and features heavily in many classic films. Blade Runner, The Matrix, Ex Machina, and A Space Odyssey all heavily depict the presence and capabilities of AI. In Blade Runner, Rick Deckard, a ‘Blade Runner,’ is sent to hunt down and terminate advanced Artificial humans. The Matrix, on the other hand, features a computer-generated dream world in which a battle between humanity and sentient machines takes place.

The aliens

The alien element of science fiction films is another classic and recognizable aspect. E.T. the Extra-Terrestrial, Aliens, The Day the Earth Stood Still, and Avatar are especially influential films featuring extraterrestrials. In E.T. the Extra-Terrestrial, viewers follow the journey of an alien stranded on Earth, while Aliens is a more action-filled movie that follows a team of space marines as they face off against hostile aliens.

Robots are a common element in sci-fi films and often play the roles of both allies and enemies to humankind. In The Matrix, robots serve as the antagonists while also remaining very human in their attitude and logic. In The Terminator, robots are portrayed as both an evil terror and a savior depending on the context. In Ex Machina, robots are depicted as intelligent, android-like machines that are becoming increasingly aware of the world around them. Lastly, in A Space Odyssey, the protagonist is accompanied by an AI robot called HAL throughout his space journey.
