twilight zone episodes that this is based on. (you'll want to see this)
i was a teenage boob when i first saw all these planet of the apes movies air on tv, i think that was the right time to watch them, since then i have discovered the great twilight zone series they used the author from in this, if you want to see similar things like this and perhaps live outside usa and is not aware of the twilight zone series, i strongly urge you to check out these episodes:
"the rip van winkle caper",
"i shot an arrow into the air,
"people are alike all over"
and numerous episodes of the last man finding female companionship, all these episodes are also available as twilight zone radio dramas. i remember hearing in a behind the scenes to this that it was extremely hot on the filming location, that makes it painful to watch them in those uniforms, i rarely like behind the scenes and commentary, usually you just end up being disappointed cause they take the magic away. i thought about rewatching all these planet of the apes movies this summer but now i'm not sure, i remember the first one was clearly the one i liked best, and the second, spoiler, brought back heston to kill him and then got a heston look alike, the series i couldn't even get hooked on.
cast my mind back a couple of years,
when it was like heaven having you near,
like a weekend full of sunshine i held so dear,
but your smile vanished and blown away is what once was here,
as your sun kissed body makes the memories come through clear,
but you've frozen since yesteryear.
