Science fiction is increasingly popular, and recent blockbusters prove it. James Cameron’s Avatar: Fire and Ash is currently a huge success in theaters, well on its way to earning over a billion dollars. Denis Villeneuve is aiming for similar results with the planned third and final Dune movie in 2026. A key reason for the popularity of both Avatar and Dune is their immersive worlds, which inspire endless fan theories and discussions while audiences eagerly await the next film.
It’s great to have a theory about something happening in a movie, but even better when that theory concerns an established idea that’s likely to remain unproven. That keeps the discussion going and prevents anyone from definitively ending it. Here are seven sci-fi movie theories that will make you see the films in a whole new light.
7) Rick Deckard Is a Replicant
Harrison Ford is known for many iconic roles, but Rick Deckard is arguably his most layered. In the film Blade Runner, Deckard, a former cop, hunts down dangerous, artificial humans called replicants. His life becomes complicated when he meets Rachael, a replicant who thinks she’s a real person. Director Ridley Scott subtly suggests Deckard might be in the same situation as Rachael, and the sequel, Blade Runner 2049, reinforces this idea with a story about a replicant working as a police officer.
6) Jurassic Park‘s Dinosaurs Are Fake
In Steven Spielberg’s Jurassic Park, scientists achieve the incredible feat of bringing dinosaurs back to life. They do this through a complex process involving ancient DNA extracted from mosquitoes that once fed on dinosaurs. This seemingly unbelievable premise has fueled speculation that the dinosaurs in the film aren’t real, with some suggesting they were created by combining the DNA of different animals.
5) Inception Takes Place Entirely in a Dream
Okay, so Christopher Nolan never makes things simple, and Inception is a perfect example! It’s about this team of criminals who sneak into people’s dreams – not to just see them, but to steal secrets or even plant ideas. But here’s where it gets really wild: they go layers deep, dreaming within dreams! It’s made so many of us wonder if the whole movie is actually happening inside someone’s head. Honestly, with everything going on with Cobb, it feels like we’re taking a deep dive into his mind, and it’s brilliant!
4) Signs‘ Aliens Are Actually Demons
I’ve always been fascinated by M. Night Shyamalan’s twists, and the one in Signs is a classic – aliens being defeated by water! But I recently came across a really interesting theory. It suggests the threat isn’t actually aliens at all, but something biblical. It makes sense when you think about it, because the creatures show up right when Graham Hess is losing his faith after his wife’s death, and it feels like he’s really battling his own inner struggles throughout the whole movie.
3) Snowpiercer Is a Sequel to Charlie and the Chocolate Factory
In Charlie and the Chocolate Factory, Willy Wonka holds a global contest to find someone to take over his chocolate empire, ultimately choosing a kind, unassuming boy. A similar search for an heir takes place in Snowpiercer, led by the train’s conductor, Wilford, but his reasons are much darker – he intends to eliminate a portion of the train’s population. Though Wilford doesn’t share Wonka’s passion for sweets, a popular theory suggests he’s an adult Charlie Bucket who used his wealth to create the extravagant train.
2) George McFly Knows About His Son’s Time Travel
In the Back to the Future movies, Marty McFly often breaks the rules of time travel. He shares things he shouldn’t and even gets involved with his own parents’ past. A Reddit user theorizes that Marty’s actions cause his father, George, to figure out that the man named Calvin he meets is actually his future son. However, George stays quiet, wanting to shield Marty’s secrets and potentially alter time himself.
1) E.T. Is a Jedi
In Spielberg’s classic film E.T., the alien isn’t ordinary – he can move things with his mind and connect with Elliot telepathically. These powers are similar to those of the Jedi in Star Wars, leading to a popular fan theory. The theory suggests E.T. is actually a Jedi stranded in the wrong galaxy, and the ending of the movie shows his people rescuing him. Some fans believe this explains why aliens resembling E.T. briefly appear in the Star Wars prequel films.
