The first trailer for Peter Jackson’s presumed franchise starter Mortal Engines premiered online earlier today, after playing in front of Star Wars: Episode VIII—The Last Jedi in select theaters this past weekend. Based on Philip Reed’s quartet of novels, the film is set in a post-apocalyptic steampunk version of Earth where it is somehow more efficient for entire cities to travel the wastelands in search of resources, rather than building new cities in resource-rich areas like humanity did the first time. Regardless, the biggest and most voracious of these cities is jolly old London, which swallows a smaller town, and all the humans on board, whole in this initial trailer.

Anyway, Mortal Engines, which based on this abbreviated first look appears to be a hybrid of Howl’s Moving Castle and the Mad Max series, is set to debut in December 2018.
