I know i saw this before 1998.
...i can't recall where or when, but i swear i watched it the first
time when i was still in high school, so sometime in the early-to-mid 90's..
I do remember seeing another version of it a couple years later that
included footage that explained how it was all done (i explicitly recall
a picture of the little kids who played the aliens, with their masks off
but still in costume.)
It stands out to this day as one of the more memorable things i EVER
watched!
