Mortal Engines is a 2018 steampunk film directed by Christian Rivers and with a screenplay by Fran Walsh, Philippa Boyens, and Peter Jackson, based on the 2001 novel of the same name by Philip Reeve, and starring Hera Hilmar, Robert Sheehan, Hugo Weaving, Jihae, Ronan Raftery, Leila George, Patrick Malahide, and Stephen Lang.
An American–New Zealand co-production, the film is set in a post-apocalyptic world where entire cities have been mounted on wheels and motorised, and practise municipal Darwinism; its movie universe is different from that of the books.
