The unlikeliest cult hit of 2004 was What the (Bleep) Do We Know? , a lecture on mysticism and science mixed into a sort-of narrative. Marlee Matlin stars in the dramatic thread, about a sourpuss photographer who begins to question her perceptions. Interviews with quantum physics experts and New Age authors are cut into this story, offering a vaguely convincing (and certainly mind-provoking) theory about... well, actually, it sounds a lot like the Power of Positive … mehrThinking, when you get down to it. Talking heads (not identified until film's end) include JZ Knight, who appears in the movie channeling Ramtha, the ancient sage she claims communicates through her (other speakers are also associated with Knight's organization). What she says actually makes pretty good common sense--Ramtha's wiggier notions are not included--and would be easy to accept were it not being credited to a 35,000-year-old mystic from Atlantis. --Robert Horton weniger
