I was watching They Live (1988) by John Carpenter and Zizek and ideology popped into my head. They Live is about a man who discovers that aliens - free enterprisers for whom the earth (their third world) is ripe for their interests as another developing planet - are essentially brainwashing people through consumer society while concentrating massive power and wealth into their own hands and of course the human power elite.
The Zizek and ideology reference is because Roddy Piper only realizes the 'truth' of the world in which he lives when he puts on sunglasses. Following Zizek, since we are already and always constituted through ideology - we are interpellated in and through ideology - in order to see the ideology we have to put our ideological lens on, we do not take off our ideological lens'.
