The Story of Mortal Engines
Mortal Engines unfolds in a future so distant and strange that it feels like fantasy. The world has been reshaped by catastrophe—and in response, humanity's solution was delightfully absurd: mount entire cities on wheels, arm them with massive engines, and let them hunt smaller settlements for resources and survival. It's a premise that shouldn't work, yet somehow it does. The film follows Hera Hilmar's Hester Shaw, a scarred young woman with a singular purpose: stop the great predator city of London before it devours everyone she cares about. What unfolds is a revenge narrative wrapped in a sprawling adventure across a wasteland of gears, steam, and rusted metal.
The story doesn't waste time establishing its world—it throws you into it, which can feel overwhelming but also exhilarating. Hester's quest pulls her into contact with Tom Natsworthy (Robert Sheehan), a sheltered citizen of London who begins to question everything he's been taught. Their unlikely partnership drives the emotional core of the film, even as massive mechanical cities clash and smaller communities fight for survival. What's striking is how the film manages to balance intimate character moments with genuinely spectacular set pieces—a feat that doesn't always succeed, but when it does, it's unforgettable.
Behind the Making of Mortal Engines
Mortal Engines stands as a bold adaptation of Philip Reeve's 2001 young adult novel, brought to the screen by director Christian Rivers in his feature directorial debut. The film represents a significant creative undertaking—an American-New Zealand co-production that drew on the talents of screenwriters Fran Walsh, Philippa Boyens, and Peter Jackson (who served as a producer). That pedigree alone signals ambition. The ensemble cast includes Hugo Weaving as the sinister Thaddeus Valentine, Jihae as the fierce rebel fighter, and Ronan Raftery and Leila George rounding out a diverse roster of characters navigating this fractured world.
The production itself was substantial, with a reported budget that attempted to match the film's visual scope. At 128 minutes, the runtime reflects the filmmakers' determination to capture the novel's complex world-building. The PG-13 rating kept the content accessible to its young adult source material's core audience. When the film released in December 2018, it arrived with considerable expectations—the kind of prestige that comes from Jackson's involvement and New Zealand's proven track record in epic fantasy filmmaking. However, the box office told a different story: Mortal Engines earned just $15.9 million worldwide, a significant shortfall that made it clear audiences weren't ready to embrace this particular vision. The critical response was mixed at best. Rotten Tomatoes settled at 26% (firmly Rotten), while Metacritic's score of 44 reflected a broader consensus that the film bit off more than it could chew. The Academy recognized the film's technical ambition with three wins and two nominations, primarily in craft categories—a consolation prize for a film that swung for the fences.
What Makes Mortal Engines Stand Out
Here's the thing about Mortal Engines: it's genuinely weird, and that's not nothing. In an era when science fiction tends toward either gritty realism or familiar superhero templates, this film commits fully to its steampunk-diesel-punk hybrid aesthetic. The production design is extraordinary—those massive mechanical cities, the intricate clockwork details, the way rust and metal dominate every frame. It's the kind of world-building that makes you want to pause and just stare at the screen, which viewers consistently praised even when they found the narrative frustrating.
Hera Hilmar carries the film with a quiet intensity, bringing genuine vulnerability to Hester's arc of vengeance and redemption. Her face—scarred and defiant—becomes the emotional anchor in a film that could've easily lost itself in spectacle. Robert Sheehan provides effective contrast as the idealistic Tom, and their chemistry works when the script gives them room to breathe. Hugo Weaving, playing against type as a villain with paternal warmth masking ruthlessness, reminds you why he's so good at making the sinister feel intimate. What's less successful is the pacing—the film tries to cram character development, world-building, action sequences, and philosophical questions about survival and morality into two hours, and something's always getting short-changed. Some viewers found the editing choppy and the narrative momentum inconsistent. That said, the film's ambition is evident in every frame. It's not trying to be a safe, focus-grouped blockbuster. It's trying to be something genuinely original, even when the execution stumbles.

Final Thoughts on Mortal Engines
Mortal Engines isn't a perfect film—far from it. But it's a film that swings hard and doesn't apologize for its strangeness. If you're tired of safe, predictable blockbusters and you're willing to forgive some narrative rough edges in exchange for genuine originality and stunning visuals, this one's worth your time. The world itself is the real star here: a post-apocalyptic landscape where survival means becoming a predator, where entire civilizations are built on treads and gears, where nothing is stable and everything moves. That's a compelling enough hook to justify the runtime, even if the script doesn't always deliver on the promise. It's a film that rewards patience and imagination from its audience—and honestly, we could use more of those.
