Steven Spielberg has shaped modern science fiction more than almost any other filmmaker. While many directors have explored extraterrestrial life through fear and destruction, Spielberg often approaches alien stories with a sense of wonder, curiosity, and humanity. His films don’t simply ask whether aliens exist—they explore how people might react when confronted with something completely beyond their understanding.
Across several decades, Spielberg has directed and produced some of the most memorable alien-themed movies in cinema history. From emotional family adventures to large-scale alien invasions, his work continues to inspire filmmakers and captivate audiences around the world.
Here’s a ranking of Steven Spielberg’s most iconic alien movies, based on storytelling, cultural impact, visual achievement, and lasting popularity.
5. The BFG (2016)
Although The BFG isn’t technically an alien movie, it often earns a place alongside Spielberg’s science fiction adventures because of its story about a young girl encountering a mysterious being from another world.
Based on Roald Dahl’s beloved novel, the film follows Sophie as she befriends the gentle Big Friendly Giant. Instead of focusing on action, the movie celebrates imagination, friendship, and courage.
Visually, The BFG remains impressive, with realistic motion capture and beautifully designed fantasy environments. While it didn’t achieve the same cultural impact as Spielberg’s biggest science fiction films, it remains a charming family adventure with plenty of heart.
4. War of the Worlds (2005)
War of the Worlds presents Spielberg at his most intense. Inspired by H.G. Wells’ classic novel, the movie tells the story of an ordinary father trying to protect his children as Earth comes under attack by a technologically superior alien force.
Unlike many invasion films that focus on military battles, Spielberg keeps the story grounded by following one family’s desperate struggle for survival. This personal perspective makes the large-scale destruction feel even more frightening.
The towering alien tripods remain some of the most unforgettable machines ever created for a science fiction film. Combined with realistic visual effects and relentless pacing, War of the Worlds delivers one of cinema’s most gripping alien invasion experiences.
3. A.I. Artificial Intelligence (2001)
Although A.I. Artificial Intelligence primarily explores artificial intelligence rather than extraterrestrial life, its mysterious ending introduces advanced future beings that have often been interpreted as evolved descendants of humanity or highly advanced alien-like entities.
The film follows David, a robotic child programmed to love, as he searches for acceptance in a world that struggles to understand him. Beneath its futuristic setting lies an emotional story about loneliness, hope, and the desire to belong.
Spielberg successfully combines philosophical questions with heartfelt storytelling, creating one of his most thought-provoking science fiction films.
2. E.T. the Extra-Terrestrial (1982)
Few movies have captured the magic of childhood as beautifully as E.T. the Extra-Terrestrial.
Rather than portraying aliens as dangerous invaders, Spielberg introduces an innocent visitor stranded far from home. The friendship between Elliott and E.T. becomes the emotional heart of the movie, reminding audiences that compassion often matters more than fear.
The film balances humor, adventure, and emotional storytelling with remarkable ease. Its unforgettable bicycle scene, memorable musical score, and touching finale have become iconic moments in film history.
More than four decades after its release, E.T. continues to inspire audiences of all ages and remains one of the greatest family science fiction films ever made.
1. Close Encounters of the Third Kind (1977)
Taking the top spot is Close Encounters of the Third Kind, the film that redefined how Hollywood portrayed extraterrestrial life.
Instead of focusing on conflict or invasion, Spielberg imagines first contact as an extraordinary moment of curiosity, communication, and discovery. The story follows ordinary people who experience mysterious encounters that gradually lead them toward one of cinema’s most unforgettable finales.
The movie stands out because it treats alien life with optimism rather than fear. Its breathtaking visual effects, atmospheric storytelling, and unforgettable musical communication sequence remain groundbreaking even by today’s standards.
Close Encounters successfully blends mystery, emotion, and scientific imagination into a film that continues to influence science fiction decades after its release.
What Makes Spielberg’s Alien Movies Different?
Many alien movies rely on large battles, explosions, and global destruction. Spielberg certainly knows how to create spectacular action, but his greatest strength lies elsewhere.
His films focus on ordinary people placed in extraordinary situations. Whether it’s a lonely child befriending an alien, a father protecting his family during an invasion, or everyday citizens witnessing impossible events, Spielberg always grounds science fiction in human emotion.
This emotional foundation allows audiences to connect with the characters before becoming immersed in the larger science fiction elements.
Spielberg’s Lasting Influence on Science Fiction
Spielberg’s approach has inspired generations of filmmakers.
Many modern science fiction movies borrow ideas that became popular through his work, including realistic emotional storytelling, sympathetic extraterrestrial characters, family-centered narratives, and visually spectacular first-contact sequences.
His films also demonstrated that science fiction could appeal to audiences far beyond dedicated genre fans. By combining emotional storytelling with groundbreaking visual effects, Spielberg helped transform science fiction into one of Hollywood’s most successful genres.
Even today, directors continue to reference his filmmaking style when creating stories about space, extraterrestrial life, and humanity’s place in the universe.
Which Spielberg Alien Movie Should You Watch First?
If you’re completely new to Spielberg’s science fiction films, E.T. the Extra-Terrestrial is an excellent starting point because of its universal themes and emotional storytelling.
Viewers who prefer mystery and thoughtful science fiction should begin with Close Encounters of the Third Kind, while fans of intense action and survival stories will likely enjoy War of the Worlds.
Those interested in philosophical science fiction can explore A.I. Artificial Intelligence, and families looking for a lighter fantasy adventure may appreciate The BFG.
Each film highlights a different side of Spielberg’s remarkable storytelling abilities.
Final Thoughts
Steven Spielberg has spent decades redefining how audiences experience alien stories. Instead of portraying extraterrestrials as simple monsters or villains, he consistently explores themes of curiosity, hope, fear, family, and human connection.
From the emotional friendship in E.T. the Extra-Terrestrial to the awe-inspiring mystery of Close Encounters of the Third Kind and the terrifying realism of War of the Worlds, each film offers a unique perspective on humanity’s relationship with the unknown.
