Very little is known about Dark Knight director Christopher Nolan’s new movie, Inception, other than it stars Leonardo DiCaprio, Joseph Gordon-Levitt, Ellen Page, Michael Caine and Cillian Murphy, and that it’s a sci-fi flick that takes place ‘inside the architecture of the mind’. Well, although the teaser trailer is due imminently we can add to our Inception knowledge with this video that shows that at some point in the film there’ll be an explosion in Paris. Someone scored this unofficial set video (the movie is currently filming in the French capital), showing some things blowing up and people blithely walking by as if nothing’s happening (does that suggest we’re inside someone’s mind at this point in the film, if no one is taking any notice of the explosion?). Anyway, take a look at the not deperately revelatory video below. It may be one of our first looks at Inception, but let’s hope the teaser is a bit more forthcoming.
