I find all those "last people on Earth" movies interesting, even the lousiest of 'em, so I have to plead guilty to liking FIVE. Having characters like a pregnant woman, a black guy and a pushy, "very German" guy (ifyouknowwhatImean) in the mix added to the interest. "A noble experiment" I'd call it, worth seeing.

For what it's worth, that's pretty much the way I see it, too. It stars William Phipps, another plus, and it's filmed in an interesting Frank Lloyd Wright house, reportedly owned by Oboler.
