But, what I really want to talk about is this one little trick he uses that I think is amazing. His character is in a stamp shop examining very carefully two incredibly rare stamps. First he shines a special stamp lamp over them and looks through a magnifying glass. Then he puts these away and looks at the stamps for a moment just under the regular light "in the store" (just stage lights, not practical lamps). He looks at them like this for a moment, then he looks up at the "ceiling," finds exactly where the "light fixture' is shining, and moves the stamps slightly to be more directly in this light.
If we follow his eyes while he goes through this little bit we will trace the stage walls to where they end, then the fifteen feet or so of fly space until we get to the lighting grid cold and functional from which hang dozens of stage lights of all sizes and colors pointed meticulously at all parts of the stage. But we know for Sterling (Lance's character), that there is simply a light fixture some four or five feet above his head.
In this bit Lance draws our attention to the patent theatricality of the moment while casually insisting that we are mistaken and that he is simply a stamp enthusiast in a dingy little shop trying to get the best view. It is completely fantastic.
