This short shows Jack Nicholson preparing for a scene in Stanley Kubrick’s The Shining. In the scene, Nicholson’s character Jack Torrance chops into a locked bathroom door to get to his wife, for whom he’s not exactly going to invite her out for some ice cream. To prepare for filming the scene, Jack gets amped up by jumping up and down in place like a boxer would, grabbing the ax and vocalizing.
The clip is from The Making of the Shining, which is a short documentary film made during production by Stanley Kubrick’s then 17-year-old daughter Vivian. The documentary is packaged with The Shining Two-Disc Special Edition as a special feature.
