The Gremlins

In Gremlins, the protagonist’s father brings home a beautiful new pet named Gizmo that he found in China. The alien species is known as the Mogwai, and they were created on a faraway planet to bring peace to adjacent civilizations before arriving on Earth. This species, however, is unstable since it reproduces quickly and goes through metamorphosis before converting into minor green troublemakers.

Gremlins was released in 1984 with a 15 rating, later reduced to PG-13 months. Nowadays, children are exposed to so much more. Thus this comedy/horror film appears moderate by today’s standards. Yet, many reviewers see the aged classic as one of the most iconic films of the 1980s. Many people who were children at the time still have fond memories of Gremlins.

Chicken Little

Ace “Chicken Little” Cluck, a little rooster who got a loser reputation after convincing everyone that the sky was falling, is played by Zach Braff in Chicken Little. A year later, Chicken Little and his buddies realize by chance that an alien invasion is taking place on Earth.

Chicken Little, based on the traditional legend “Henny Penny,” depicts aliens as foes, but not in a threatening way. In reality, these characters aren’t even the film’s primary focus. It’s more about Ace’s relationship with his dad. This film is healthy enough for children to enjoy but not so childish that adults would find it uninteresting. Even an adult could watch it.

Home (2015)

The color-changing alien race Boov relocates all humans to the Australian outback and makes Earth their new home in Home. Jim Parsons, best known for his role as Sheldon in The Big Bang Theory, provides the voice of the extraterrestrial protagonist Oh.

Christopher Lloyd

Tim O’Hara (Jeff Daniels) is a struggling news producer when a Martian (Christopher Lloyd) crashes landings in his town. Tim initially sees the Martian as a way to relaunch his producing career. When an evil governmental corporation attempts to capture the alien, they form an unusual bond.

My Favorite Martian follows Uncle Martin, as Tim refers to the Martian, on his amusing exploration of Earth. Lloyd’s performance as Martin is both funny and weird. The film was not well received then, but a rewatch reveals that it needed to be more appreciated.

The Iron Giant

The Iron Giant is a massive robot, but he’s also an extraterrestrial super-weapon, making him something of an alien. The film is set in 1957 in Maine when Hogarth discovers the massive contraption in the woods near the fictional hamlet of Rockwell. Jennifer Aniston, Christopher McDonald, and Vin Diesel star as the metal-eating invader in The Iron Giant.

The narrative of a nine-year-old boy’s friendship with a massive mechanical alien immediately became famous among children. The Iron Giant evoked nostalgic feelings in people worldwide and is an underappreciated animated film from the 1990s.

Space Jam (Live action & Animation)

Swackhammer, the main enemy of Space Jam, is voiced by Danny DeVito. When he learns about the Looney Tunes, he instructs his extraterrestrial collaborators to bring the cartoon characters to him so he may enslave them and make them into new attractions for his Moron Mountain theme park.

After agreeing to resolve their differences over a basketball game, the aliens capture Michael Jordan while the Warner Bros. icons grab the talent of some of the top NBA players.

The fun film has one of the most vital first impressions and charming characters voiced by Dwayne Johnson, Justin Long, and Gary Oldman. Many people critique Planet 51’s slightly distinct animation style. Nonetheless, due to the extraterrestrial dramatis personae, it engages young viewers, and many fans see it as one of the best-animated movies of the 2000s.

E.T, the Extra-Terrestrial

They apologize to one other while searching for a plant that could become an energy source for their people. Odd World is a whimsical look at generational trauma that incorporates a variety of strange animals. The best example is Splat, a bioluminescent creature from Avalonia who becomes Ethan’s companion. The character was well-liked by the audience.


The titular villainous protagonist of Megamind arrives in Earth’s Metro City after being sent away as a young alien. At school, he meets his competitor, Metro Man, who has superpowers and is far more popular than him in everything. Megamind quickly determines that he is doomed to pursue a life of villainy due to jealousy and resentment. The soundtrack has rock music that reflects his bad-guy persona.

Will Ferrell play the titular extraterrestrial in a comic role? The film also has an all-star voice cast, which includes Ben Stiller, Brad Pitt, and Jonah Hill. Megamind is another example of a DreamWorks Animation film that children and adults can appreciate.
