I've heard of that film but I don't think I've ever seen it.
It's from that perspective that I don't find it wildly original - but then such ideas have never been bolted onto an action filled heist movie so that is a slightly different variation on the theme. Which helps to add some blockbuster-y goodness to the film.
I believe Nolan himself has also stated pre-release that he was influenced by The Matrix
, The Thirteenth Floor
and James Bond
I imagine Bond enters the equation in the action side and that would certainly seem the case with one of the action sequences of the finale.
