What is the sound of one hand clapping? Does a falling tree make a sound if no one is there to hear it? Do these questions interest you? Then you’re sure to enjoy the sequel to the underground movie hit, “What the Bleep Do We Know?!“.

I wondered if a director’s cut–with more material and several new interviews–would be more interesting than the first, groundbreaking, “What the Bleep” movie. “Down the Rabbit Hole” is not only more interesting, but the material is more clearly presented. The new interviews shed more light on quantum physics principles, and the new animations are positively captivating in their clarity. (Some, like the double-slit experiment animation, are freely available for download and are being used in school physics classes.)

The interviews with Dean Radin Ph.D., on the nature of intention, stand out as the most interesting new material in the film. Radin’s work examines how intention can affect the outcome of physical experiments in present time, or in past time. While some of the presentations (such as the nature of entanglement) can be confusing Radin’s work is clear and raises many questions on the nature of consciousness and time itself.

What The Bleep: Down the Rabbit Hole brings quantum physics to life and illustrates ideas and concepts that are otherwise abstract and non-intuitive. I won’t say that you’ll actually understand all of the material, and some of the interviewees enjoy expounding on the weirdness of it all without explaining anything. With an open mind, I think you’ll find that What The Bleep: Down the Rabbit Hole will alter your perception of what you consider “real”.
