Everyone has their own version of reality.  This includes filmmakers.  They create and manipulate our perceptions of reality to suit a purpose, whether it be artistic or monetary.  Our job as the audience is to decide whether or not we’re willing to be manipulated.  I am perfectly willing to be manipulated when it comes to watching a movie.  The ones I like best are those that I know could never really happen or those that leave me more than a little confused.  Anyway, I think there has to be a better word for it than “reality” but I just can’t seem to think of one right now.  The power of cinema is the ability to alter our perceptions for a short time and escape our current circumstances.  I don’t remember who it was that said that the film/camera was the only way to capture reality and thus the only pure art form (feel free to jump in as I’m unsure about this) but of course, I totally disagree.  The camera is more like an intruder into reality and because of its presence, is more likely to alter reality and change the natural course of events.  It interferes with spontaneity.
