Found in an old sci-fi magazine of mine called Fantastic Films from 1978:
They actually call them 'home movies!' :p
Yikes, I'd have to sell a kidney to buy those 8 minutes worth of the movie! (sorry, I should say ALMOST 8 minutes...)
I've consulted an Inflation Calculator, and the 2012 prices are as follows:
B&W silent version: $30.64
Color silent: $61.46
Color & sound: $102.54
I bet there are people on eBay selling them for more than that now, actually!
