Surrogates – So many questions

I just watched the trailer for the upcoming Bruce Willis film Surrogates, and the concept is pretty interesting.  To be honest, I am not familiar with the original comic book series that it is based on, the concept seems rather interesting:

I’m not sure how interested I am in yet another Bruce Willis action film however, the state of the world in the film is more than enough to get me to see the film.  To me, it seems a little bit like the Matrix, without the artificial virutal reality world. It seems that in Surrogates people are able to do whatever they want, whenever they want without the usual physical limitations. It’s fascinating to think about living in a world where you can we whoever you want, and do whatever you want without any sort of ‘real world’ implications on yourself. It raises so many thoughts about how this would effect our humanity and day to day lives if we are not achored in a world with direct consequences for our actions

I am interested in learning much more about the technology, and how society changed to make this so prevalent. Who made the surrogates? How were they sold/given to people?  How do the real people manage never leaving the house? and How did society come to accept this?
