I am convinced that this giant robot, from the 1957 movie Kronos: Ravager of Planets, is perhaps the very best of the abstract giant robots. And by "abstract," I mean Kronos here looks basically like a modernist building — just a big box on giant struts with a spherical head topped by two antennae. Sure there's some backstory here, like a flying saucer crashed in Mexico and suddenly there was this giant robot who is mind-controlling everybody so it can eat electricity or atomic bombs or something. Really, though, all you need to know is that there is a hulking robot building thing roaming the countryside, and being followed by three intrepid robot geeks wearing awesome coveralls that say "Labcentral" on the back. Damn, I want those coveralls. And that abstract giant robot! Here I've put together the very best of the giant robot scenes for you. Watch Kronos from far away, from up close, and in full burnination mode! [Kronos via IMDB]
