Glad all my rare earth investment is in Unobtainium.
Yes Sir! I’m heavily invested as well.
Cameron pissed off all of Hollywood when he actually USED that as the mineral causing the strife in Pocahontas Avatar.
"Unobtanium" is a movie development standard placeholder (like "MacGuffin) in scripts or treatments, usually replaced by some name at the last minute.
By actually USING the term, Cameron took that away and I think Hollywood is still looking for an alternative.
