The Fifth Element is a wild, over-the-top sci-fi action spectacle that, while perhaps less philosophically heavy than some others on this list, matches 'Rick and Morty's' energy and unique visual style. Luc Besson's futuristic opera is set in the 23rd century and follows a cab driver who becomes involved with a mysterious young woman who holds the key to saving the world. The film is a feast for the eyes, thanks in part to designs by French comic artists Jean 'Moebius' Giraud and Jean-Claude Mézières, and features eccentric characters, elaborate costumes designed by Jean-Paul Gaultier, and a blend of action, comedy, and adventure. It's pure, unadulterated sci-fi fun.

The Lobster shares 'Rick and Morty's' taste for dark, absurdist humor and satirical world-building. Directed by Yorgos Lanthimos, this unique film is set in a dystopian society where single people are required to find a romantic partner within 45 days or be transformed into animals. Colin Farrell stars in this deadpan comedy that is a bizarre and insightful commentary on societal pressures surrounding relationships. It's deliberately awkward, darkly funny, and utterly original, creating a strange, unsettling world that feels both alien and uncomfortably familiar, much like the twisted realities Rick and Morty often stumble into.

The Truman Show might not be traditional sci-fi, but its central premise of a man living in a constructed reality resonates with the 'what is real?' questions often posed in 'Rick and Morty'. Jim Carrey gives a career-defining performance as Truman Burbank, whose entire life since birth has been the subject of a massively popular reality television show, unbeknownst to him. Directed by Peter Weir from a prescient screenplay by Andrew Niccol, the film is a poignant and often humorous exploration of authenticity, surveillance, and the desire for freedom. It's a thought-provoking commentary on media and reality that feels even more relevant today.

For fans of the grand, hard sci-fi concepts explored in some 'Rick and Morty' episodes, Interstellar offers an epic journey through space and time. Directed by Christopher Nolan, the film follows a group of astronauts who travel through a wormhole in search of a new habitable planet for humanity. The movie grounds its ambitious story in real scientific theories, with physicist Kip Thorne serving as a consultant on concepts like wormholes and black holes. It's a visually stunning and emotionally resonant film that tackles profound themes of love, loss, and humanity's future on a cosmic scale, featuring incredible visuals and another powerful score from Hans Zimmer.

While not comedic, Blade Runner shares 'Rick and Morty's' fascination with deep, existential questions, particularly concerning identity and what it means to be human. Ridley Scott's neo-noir sci-fi masterpiece, based on Philip K. Dick's novel, is set in a dystopian 2019 Los Angeles where a detective hunts down bioengineered androids known as replicants. The film is renowned for its incredible, rain-soaked production design (heavily influenced by artist Syd Mead) and Vangelis' atmospheric score. It's a slow-burn, philosophical detective story that has sparked endless debate about its themes and has had a lasting influence on the science fiction genre.

Christopher Nolan's Inception shares 'Rick and Morty's' love for building complex, layered worlds based on intricate rules, even if those worlds are inside the human mind. The film centers on a group of extractors who use dream-sharing technology to steal information from people's subconscious. Their latest mission, however, is the reverse: to plant an idea in someone's mind, known as inception. The movie is a thrilling, visually spectacular heist film that unfolds across multiple levels of dreams, constantly challenging the audience's perception of reality. Nolan's meticulous planning, combined with stunning practical effects and Hans Zimmer's powerful score, creates a truly immersive and mind-bending experience.

The Matrix is a landmark sci-fi film that, like 'Rick and Morty', makes you question the very nature of reality. It follows Neo, a computer programmer who discovers that the world he knows is actually a simulated reality created by machines, and that he is humanity's last hope. The Wachowskis' film blended philosophical ideas (drawing from sources like Plato's Allegory of the Cave and Baudrillard's Simulacra and Simulation) with groundbreaking action choreography and visual effects, including the iconic bullet time. Its exploration of what is real and the struggle against oppressive systems has had a massive cultural impact and continues to resonate.

If you enjoy 'Rick and Morty's' willingness to dive headfirst into complex and often paradoxical time travel scenarios, then Predestination is a must-see. Based on the classic Robert A. Heinlein short story "All You Zombies—", this film is a tight, mind-bending sci-fi thriller centered around a Temporal Agent who travels through time to prevent crimes. His final assignment involves tracking down a elusive terrorist, leading to a series of events that challenge everything he knows about time, identity, and causality. Ethan Hawke and Sarah Snook deliver powerful performances in this low-budget gem that manages to pull off one of the most intricate and surprising time travel plots ever put to screen.

Mr. Nobody feels right at home alongside 'Rick and Morty' for its ambitious exploration of choice, consequence, and parallel realities. The film follows Nemo Nobody, the last mortal on Earth in the year 2092, who recounts his life story. However, his story branches into multiple possible timelines based on pivotal choices made throughout his youth. It's a visually stunning and philosophically rich narrative that uses concepts from quantum physics like the butterfly effect to weave a complex tapestry of potential lives. Jared Leto gives a compelling performance across different ages and realities in this intricate European co-production that constantly makes you question the nature of destiny and free will.

Donnie Darko has become a bona fide cult classic for good reason, and its blend of sci-fi, philosophical pondering, and dark, mysterious tone resonates with the feel of 'Rick and Morty'. Set in the late 1980s, the film follows a troubled teenager who is visited by a mysterious figure in a rabbit suit named Frank, who tells him the world is going to end. This kicks off a series of strange events involving time travel, destiny, and the fabric of reality. Director Richard Kelly crafted a film that is both enigmatic and thought-provoking, fueled by a fantastic soundtrack and a young, talented cast including Jake Gyllenhaal and Maggie Gyllenhaal. It's a movie that encourages discussion and interpretation, much like unpacking a complex 'Rick and Morty' episode.

Eternal Sunshine of the Spotless Mind is another Charlie Kaufman-penned gem that delves into the messy, complicated landscape of the human mind, much like 'Rick and Morty' often does with its characters' psyches. Directed by the visually ingenious Michel Gondry, the film explores what happens when a couple decides to undergo a procedure to erase each other from their memories after a painful breakup. It's a non-linear, surreal journey through fading recollections, filled with incredible practical effects and visual metaphors. While less overtly comedic than 'Rick and Morty', it shares that show's willingness to tackle profound, often painful, emotional truths through a high-concept sci-fi lens. Jim Carrey and Kate Winslet give standout performances in this truly special film that won an Academy Award for Best Original Screenplay.

For fans of 'Rick and Morty's' comedic take on grand cosmic scale, The Hitchhiker's Guide to the Galaxy is an absolute must-watch!
