What is it with Nicolas Cage at the moment? It only seems like a few weeks ago that he was compulsively bursting into flames, and whizzing about on his moped in 'Ghost Rider', and now he appears in 'Next' as a man with the ability to see two minutes into the future! It sounds like the premise of an M. Night Shyamalan movie, but in fact it's yet another film based on a story by Philip K.Dick.
Imagine if there were a whole set of people who could see 2 minutes into the future. They could get together, and form a chain, enabling them to see hours and days into the future. In such a scenario, the individual at the base of the chain sees one of his comparably-afflicted friends, 2 minutes into the future, telling him what HE can see 2 minutes into his future, and he, in turn, sees a third individual telling him what HE can see 2 minutes into his future, and so on.
Or perhaps this would work with just two such afflicted individuals. Individual A sees 2 minutes into his future where individual B is telling him what he can see 2 minutes into his future, but individual B sees individual A telling him what he can see 2 further minutes into the future, and so on.
In fact, what if the single Nicolas Cage character just spent all his time writing down what he sees two minutes into the future? Right now, he would see what he's writing down 2 minutes into the future, which would describe what happens 4 minutes into the future, which, in turn, is a description of what happens 6 minutes into the future, and so on.
