As a self-proclaimed sci-fi connoisseur, I'm blasting off to bring you a list of the best Hollywood sci-fi movies that are out of this world. Buckle up, folks! We're starting with the grand-daddy of them all, "Star Wars." It's like the Beatles of the sci-fi world, everyone knows it, and if you don't, what asteroid have you been living under? Then there's "The Matrix," which had us questioning reality and fashion choices in the late '90s. And let's not forget "Inception," a movie so brain-bending, it has us all still wondering if the top stopped spinning. So, grab your popcorn, and let's rocket towards a sci-fi movie marathon!
