Here's a treat: an hour-long oral history concerning the making of The Shining, posted online for free. Cancel your lunch plans, Kubrick fans, it's happening!
The film, called Staircases to Nowhere, features interviews with tons of people directly involved in making The Shining, including Jan Harlan, the Producer; various camera people; Christiane Kubrick (!); and Brian Cook, the First Assistant Director...among many, many others.
If you're a fan of The Shining, you shouldn't miss Vivian Kubrick's documentary about The Shining, which she made during the production (it's typically included as a bonus feature if you buy the movie). Then there's Room 237, which is an interesting documentary, but more about obsession than about the film itself.
