The question occured to me while watching
The Italian Job remake trailer: which current films are gonna go through the re-think machine for future generations to discover first-hand?
Of the remakes I can think of, they generally seem to break down into 5 specific categories
1) to exploit developments in film-making technology - updated effects, inflated budgets etc. e.g.
Time Machine 
2) to realise the specific vision of a filmmaker e.g.
Psycho 
3) to translate a foreign success to the English-speaking world e.g.
The Vanishing 
4) to update a classic story, cast teen actors and set it in a high-school somewhere, e.g.
Swimfan 
5) to rake in bags and bags of cash
So what currently new flicks will be cropping up
again in our film-going futures?
