I just rewatched The Poseidon Adventure the other day. It was on AMC while I was taking a sick day.
And what struck me about it how it is now not just a fun disaster film, but has become a historical document.
I absolutely love its 70's backgrounds. Look how shabby everything was in the 70's! How abysmal and tawdry looking! And this is supposed to be a luxury cruise liner. If you had a cruise liner or resort that looked like these sets now, you'd be out of business in two days. And look at the horrible clothes. Not just the styles, but the wretchedly low quality of the clothes. Observe how nobody looks like they're taken a shower in a couple of weeks, even before the disaster hits.
It's awesome.
