Peter Jackson’s Mortal Engines could be the US$100 million film flop of 2018 – so what went wrong?
- A baffling story that lacks a hook, a debutant director, almost no stars, big competition, a massive marketing misfire – Universal has a holiday bust
- Studio hoped to launch a new sci-fi fantasy franchise with Mortal Engines, but woeful reviews and terrible ticket sales look to have doomed that idea

Every year brings at least one hugely budgeted movie that doesn’t just sink at the box office, but positively plunges like a flightless turkey. It’s the kind of epic miscalculation that makes a studio re-evaluate its entire year.
For 2018, Universal/Media Rights Capital’s Mortal Engines has just weighed in as the biggest holiday bust – a monster of a miss. Or, as Exhibitor Relations analyst Jeff Bock told Variety: “This is a true Christmas disaster and a lump of coal for Universal.”
Mortal Engines, co-written by Peter Jackson and Fran Walsh, grossed a paltry US$7.5 million in its North American debut over the weekend, from more than 3,100 screens. That only deepened the hole for the sci-fi fantasy spectacle, which has grossed US$34.8 million overseas on a reported US$100 million budget – meaning that the movie could lose more than US$100 million after marketing costs are factored in.
The common denominator among all those hit films, of course, is that they are the latest entries in existing franchises.
