| Jan 5, 2013 at 14:45 | comment | added | Dave Tweed | I should also add that calling this subtance (the room-temperature superconductor) "Unobtanium" in Avatar really cracked me up. That term is an engineering in-joke from long ago, meaning any item that you need but can't get. I've often wondered whether James Cameron intended for that name to be replaced with something else before the script was finalized for shooting. | |
