The film has a nicely weird story. On a scorched future earth cities have been made mobile. The travelling city of London drives around the globe to literally eat up smaller cities in order to use their resources. In this film London symbolises the West with its greed and destruction. The face of this is Thaddeus Valentine, well played by Hugo Weaving (Agent Smith in The Matrix).
There are also people who do not live in these mobile cities, but they are hunted by all kinds of rogue towns. One such person is Hester Shaw who has plans for Valentine. Together with Tom she drops off London and falls into the hands of a rebel group who the two are going to help to prevent London (the West) to break through the wall guarding the East.
The weird cities themselves, but especially the weird machines bring memories of films such “Mad Max“. “Mad Max” is much rawer though. Especially the obligatory romance and jokes of “Mortal Engines” make it a too typical Hollywood film.
The only thing that is somewhat uncommon is that the West is bad and the East actually wins. Oops, I gave away the end.
“Mortal Engines” is an amusing dystopian sci-fi spectacle, but not a terribly good one.
