At 1:13:16 into the Criterion Collection DVD version, when the shot changes to Yogoro (played by Gô Katô)---just as he begins to verbally caution the lord and his retainers (after having delivered the petition)---there is a boom mic bobbing up and down about 10 inches above Gô's head, just on the edge of the frame. Then, in the same shot, as Gô is rising to his feet, the mic can be seen in front of his forehead. The mic then casts a shadow on his forehead just before the shot changes to a closeup of his face.
