Children of Men 

In the opening of the film we see that a bunch of people gathering up to watch the news.  The news has states about the death of an 18 year old which seems odd. As the film continues it a news reporter states that the 18 year old person was the youngest person in the world which tells me that there is a crisis in fertility.  I can immediately tell who the main character is (Clive Owen) everyone is so interested on what is on the news that he just walks out of the coffee shop like he doesn't really care. Everyone else in the room seemed very sad that this had occurred but that didn't stop him as he just skipped the line and got himself a coffee.

While the main character walks away the camera follows him which catches are attention. The protagonist can be seen that once he has left the coffee shop he takes out a flask and starts putting alcohol in his coffee which suggests that he is trying to release some sort of stress or he is an alcoholic and he has had a rough day. 

The opening is filmed in London in the year 2027,  However London doesn't look high tech like you would expect it to be instead it looks like the London we know today, It looks dirty and polluted. As soon as the main character has finished putting alcohol in his coffee a bomb goes off in the coffee shop that he was just in. The bomb exploding sort of tells us that London is dangerous with low chances of survival by just going to get a cup of coffee. After the bomb goes off a woman comes out of the store with one arm missing, it seems like no one cares, no-one is seen calling the ambulance or police. The city is also filled with bin bags suggesting that waste has not been collected in sometime.
