Stanley Kubrick decided that having the hedge animals come alive, as they do in the novel, was unworkable due to restrictions in special effects, so he opted for a hedge maze instead.

The maze was constructed on an airfield near Elstree studios, by weaving branches to chicken wire mounted on empty plywood boxes. The maze was shot using an extremely short lens (a 9.8mm, which gives a horizontal viewing angle of 90 degrees) which was kept dead level at all times, to make the hedges seem much bigger and more imposing than they were in reality.

The photograph dated 1921 at the end of the film was a genuine 1920s photo, with Jack Nicholson’s head airbrushed onto the body of another man. Stanley Kubrick originally planned to use extras and shoot the photo himself, but he realized he couldn’t make it look any better than the real thing.

At the time of The Shining’s release, it was the policy of the MPAA to not allow the portrayal of blood in trailers that would be approved for all audiences. Bizarrely, the trailer for The Shining consists entirely of the shot of blood pouring out of the elevator. Stanely Kubrick convinced the board that the blood flooding out of the elevator was actually rusty water.
