As one of the film's characters gushes early in the proceedings, 'The moment we acknowledge the quantum self, we say that somebody has become enlightened'. A moment in which 'the mathematical formalisms of quantum mechanics [...] are stripped of all empirical content and reduced to a set of syrupy nostrums'." Journalist John Gorenfeld, writing in Salon, notes that the film's three directors are students of Ramtha's School of Enlightenment, which he says has been described as a cult.

Down the Rabbit Hole - Quantum Edition multi-disc DVD set was released, containing two extended versions of What the Bleep Do We Know!?, with over 15 hours of material on three double-sided DVDs.
