All I'd like to mention is how I felt after seeing Cache/Hidden, forget the whodunnit, forget that one remarkable blooper with the shadow of the film camera, no this was far more personal.
From a young age you do and say things which seem pretty innocuous at the time, whether telling white lies, teasing people or doing things that you know are wrong and maybe laying the blame on someone else. What the heck! what do all these little things amount to? Five minutes later it's forgotten, or is it?
For me, the cache, the hidden represent those little things done by us to others throughout our lifetimes, pushed out of sight and out of mind, meaningless and momentary. What we can't see is how these often tiny events affect the lives of the recipients, the little boy/girl teased because they had something slightly different about them, the person who received a punishment because of something you did, how much of a mark did it leave?
I couldn't help but think way into my own past at people whose lives I may have affected and also back at people who affected mine.
A few years ago I did a preliminary course before I could do another one to help set up my own business, as far as I knew I was in a room full of strangers till the names were read out. One name screamed out at me, a name I hadn't heard for probably 25+ years but straight away I found myself tensing up and searching the room for the person, 25+ years ago a local thug had made my younger brothers life hell until we turned the tables on him, I searched for this hard man and recognised his face, only to see a feeble man reduced by years of confinement and drugs to a mental wreck. Although after I felt pity for what he'd become, I couldn't get over my initial rection.
I would hate to think that I had affected anyone else in such a manner but will I ever really know, we each carry our own cache and if we're lucky they'll remain hidden.
I'd like to believe that it was at least partially Haneke's intention to make us look into our own individual cache.
