The video shows Jackman recording ADR (automated dialogue replacement) for Logan. But rather than looping actual dialogue, he’s looping his breath and growls from a fight scene toward the end of the film.
Jackman pantomimes the whole sequence in the recording booth, slipping easily into the feral Wolverine persona he’s been playing for the past 17 years. But maybe the most fascinating moment comes right at the very end of the video when he drops out of Wolverine fight mode and delivers a casual “hi” to the camera.
