In 1980, Stanley Kubrick, who had earlier created landmarks in the genres of black comedy (Dr. Strangelove) and science fiction (2001: A Space Odyssey), released his masterpiece of modern horror, The Shining. Over 30 years later we’re still struggling to unearth its hidden meanings. Rodney Ascher’s wry and provocative documentary Room 237 (review) fuses fact, fiction and speculation through interviews with both fervent fans of the film and scholars, creating a kaleidoscopic deconstruction of Kubrick’s controversial classic. It comes to Blu-ray and double-disc DVD from IFC Midnight on September 24, 2013.

Many movies lend themselves to wide-ranging interpretations, but few as rich and mysterious as The Shining, Stanley Kubrick’s adaptation of Stephen King’s bestselling novel. In Rodney Ascher’s Room 237, we hear from people who have developed complex theories about the film and believe they have decoded the hidden symbols and messages buried in the late director’s unforgettable shocker, in which a family man (played by Jack Nicholson) descends into madness while serving as the off-season caretaker of a deserted old hotel. The Shining received mixed reviews upon its initial release, but over the decades its stature has only grown, with Steven Spielberg and Martin Scorsese ranking it among the greatest horror films ever made.

Carefully examining The Shining inside and out, and forwards and backwards, Room 237 is equal parts captivating, provocative and pure pleasure. It gives voice to the fans and scholars who espouse these theories, reworking Kubrick’s film to match their ideas and intercutting it with layers of dreamlike imagery to illustrate their streams of consciousness. Sometimes outrageous, always engaging, the words of the interviewees are given full force by Ascher’s compelling vision.

An Official Selection at the 2012 Sundance, Cannes and Toronto film festivals, and winner of the Best Director prize at Fantastic Fest, Room 237 received a theatrical release by IFC Films in top markets and earned glowing reviews.

On September 24, the same day that Room 237 arrives on Blu-ray and two-disc DVD, Stephen King will publish Doctor Sleep, a sequel to The Shining. In the new novel, Danny Torrance, the child who escaped his violently insane father at the end of the original book, is now a middle-aged New Englander whose psychic gift of “shining” provides comfort to the dying patients in a nursing home.
