The woman behind the wizard #HarryPotter

Steven Spielberg once said he was opposed to "making-of" documentaries, because they spoil the magic. Director's cut DVDs, with their extras, has caused Spielberg to reconsider.
Even so, on the weekend of the first-of-two-parts final Harry Potter movie, some fans may feel the same way about the documentary A Year in the Life of J.K. Rowling. Could it be the less one knows about the creative process behind Harry Potter, the more one is apt to enjoy its fantasy world?
It helps that A Year in the Life is respectful of both its material and its audience. The film shows how a novel goes from imagination to print. In the case of Harry Potter and the Deathly Hallows, that meant secrecy, from the manuscript being locked away in a suitcase to the book-signing at midnight on the day of Deathly Hallows' release.
A Year in the Life is intimate and sensitive, a portrait of the artist dealing with the pressure of knowing the world will be hanging on her every word. (CBC News Network; 7 and 10 p.m.)
