I watched this movie while in the train, going back to college after Diwali break. I'd heard of it and knew it was in the Imdb top 250 list, with an 8.1 rating.
I found it a really commendable piece of work, especially the single shot sequences and the attention to smaller background details, something which if the makers had overlooked would be a major flaw.
The film begins with newsreaders announcing that the youngest person on earth has died, later revealing how humans have become infertile since the last 18 years. What such a situation would lead to has been brilliantly depicted, with people forming groups to pray to god to forgive them for their sins, to take away the curse of infertility; civilisations across the world have collapsed and Britain is the only standing authority. The immigrants to Britain are treated like trespassers and deported to 'fugee' camps or shipped back.
The picture painted is gruesome, with ruthless government, roadside gypsy troops that attack passers-by, a rebel group called Fishes which claims to help the immigrants, but is revealed to have a propaganda of its own.
Action sequences abound, so do situations that show how the world could to go to ruin in the absence of the innocence of children. Michal Caine puts in a brilliant performance as Jasper, Theo's confidante and the only person they can trust.
The plot revolves around how the journey for a miraculously pregnant immigrant girl to the safety of the sea, becomes the most challenging one for her and her escort, Theo. The Fishes give them the initial safehouse, but Theo overhears their plot to kill the girl and use the baby to gain their own political ground. Theo escaped with the girl and they face an infinity of hurdles to reach the sea to board the good ship The Tomorrow. Only when the baby is born and people see it, hear it cry, do they get a clear passage to move on. A heartwarming shot of armyman and terrorist both going silent, hearing the baby cry, and letting Theo and the mother go, brings out the genius of the film.
