was unaware of the significance of the line, and nearly used a different take. Carson later used the Nicholson clip to open his 1980 anniversary show on NBC. During production, Kubrick screened David Lynch's Eraserhead (1977) to the cast and crew, to convey the mood he wanted to achieve for the film. Steadicam The Shining was among the early half-dozen films (after the films Bound for Glory, Marathon Man, and Rocky, all released in 1976), to use the newly developed Steadicam, a stabilizing mount for a motion picture camera, which mechanically separates the operator's movement from the camera's, allowing smooth tracking shots while the operator is moving over an uneven surface. It essentially combines the stabilized steady footage of a regular mount with the fluidity and flexibility of a handheld camera. The inventor of the Steadicam, Garrett Brown, was heavily involved with the production of The Shining. Brown has described his excitement taking his first tour of the sets, which offered "further possibilities for the Steadicam". This tour convinced Brown to become personally involved with the production. Kubrick was not "just talking of stunt shots and staircases". Rather he would use the Steadicam "as it was intended to be used — as a tool which can help get the lens where it's wanted in space and time without the classic limitations of the dolly and crane". Brown used an 18 mm Cooke lens that allowed the Steadicam to pass within an inch of walls and door frames. Brown published an article in American Cinematographer about his experience, and contributed to the audio commentary on the 2007 DVD release. Kubrick personally aided in modifying the Steadicam's video transmission technology. Brown states his own abilities to operate the Steadicam were refined by working on Kubrick's film. For this film, Brown developed a two-handed technique, which enabled him to maintain the camera at one height while panning and tilting the camera. In addition to tracking shots from behind, the Steadicam enabled shooting in constricted rooms without flying out walls, or backing the camera into doors. Brown notes that: This required the Steadicam to be on a special mount resembling a wheelchair, in which the operator sat while pulling a platform with the sound man. The weight of the rig and its occupants proved to be too much for the original tires, resulting in a blowout one day that almost caused a serious crash.
