Opening sequence (Children of Men)

The opening sequence i have choosen is Children of men, the colours used in the opening sequence are quite dull and boring, there is a lot of grey and black which suggests depression and upset, the emotions of the people suggest this too, we're introduced to our first character (Clive owen) who unlike everyone else in the cafe he isn't affected by the news story of "Baby" Diego Murdered, it's clear to us that it's set in the future as it says the boy died in 2027, we follow Clive owen out of the coffee shop in a handheld motion, if it was anything else like a birds eye view it wouldn't be as effective and this gives the sense of realism as if we're in the film, the emotion of the character is quite relaxed and he could be seen as depressed as he takes out a bottle of alcohol and puts it into his coffee, we are then faced with a loud explosion which seems to be from the coffee shop, this shocks the audience as the character (Clive owen) was just there at the shop, it adds a lot of questions to the audience, for example, why is there no children and why was there a exploision.
