This is a great movie, it gave me so much to think about. It provides an insight about feeling safe while you are being watched, in this film it's a movie producer but although it doesn't directly tell it, or maybe it doesn't tell it at all, it could have referring to your parents watching you or why some people believe in god and feel safe with the thought of god watching over them. And the best part is that it doesn't dictate anything, this movie is nearly like a poem, you can understand it in many different ways, and everyone watching it can understand or see something different from it. And the best part is that it has an open ending and you ask yourself what may have happened. I believe the writer knows the human psychology very well.
