This seems to be about some modern Godzilla movie. I was hoping to find out how the unusual noise was made in the originals.

I watched a documentary once that claimed the source (manipulated of course) was the sound of a metal gate opening.

Wikipedia says it was created via "...rubbing a resin coated glove along the string of a contrabass and then slowing down the playback" http://en.wikipedia.org/wiki/Godzilla
