Hell, upside down
The Poseidon Adventure, one of my favourite 1970s disaster movies [when they became two-a-penny], not just because it is a cracking race against the clock survival quest, nor due to the [as with that other great ship disaster movie A Night To Remember, 1958 ] interesting commentary on class and social interaction, but because of its great upside-down frame of reference.
I remember as a child playing on the stairs of the 2 up 2 down cottage I lived in, feet up the stairs and head down, marvelling at how strange the architecture looked ‘wrong-side up’. In fact how ship-like things became, especially in relation to doorways to rooms with their now large ‘skirting board’ step barriers [like submarine hatchways].
Perhaps the surreality of the situation minds us of disasters and dreams? How else outside the funfair Mystery Mansion (Haunted House) Ride house could whole structures be turned literally up-side-down without a Wizard of Oz house-lifting tornado.
