It's difficult to keep anything fresh for an audience these days. With technology being what it is people seem to know everything there is to know about a film before you've even made it.
But, in each case, as a filmmaker who's been given sizable budgets with which to work, I feel a responsibility to the audience to be shooting with the absolute highest quality technology that I can and make the film in a way that I want.
I don't particularly enjoy watching films in 3D because I think that a well-shot and well-projected film has a very three-dimensional quality to it, so I'm somewhat sceptical of the technology.
