Warner Bros. selected the Title
From what I've gathered, Tom Graef originally entitled it THE GARGON TERROR, but after he sold it to Warner Bros. (Exactly how was he able to attain that near-impossible feat?), the Warner's executives retitled it TEENAGERS FROM OUTER SPACE to obviously sell it to the Teenage Drive-In market.
I'm curious as to how much they paid him for the legal distribution rights.
Could be considered one of the very first Indie Films.
I often wondered how it would have been if Graef had a bigger budget, better effects; etc. Within the shoddy, but oddly appealing no budget, there was an interesting story that was struggling to get out.
Notice how the first half resembled TERMINATOR?
Hmmmmmmmmmmmmmmmm.
