The 1953 version.
This is one film that doesn't rely on CGI, there wasn't any in the 1950's and yet manages to be better than a lot of sci-fi movies made. Even the remake with all of its advantages didn't quite seem as good. The martians and their machines are very well built with a lot of detail. If you haven't seen this version, you should.
Now the battle is on to save humanity and the planet, the aliens have the technology, no weapon thrown at them has an impact. Nothing seems to be able to stop them. Is history about to repeat itself but with a difference? Instead of one country invading another and then settling it. It this about to be done to us? Are we the primitive tribe about to be wiped out?
