Steven Spielberg's up dating of War of the Worlds discards the idea of cylinders falling from the sky like meteors, as conveyed in H.G. Wells' story, as well as Orson Welles' 1938 radio version.

Spielberg's aliens arrive in a different manner altogether that brings their status as outsiders into question: they've been here before, and their invasion infrastructure may already he here, waiting to be activated.
