Question: At the end, when Jefferey shoots Frank in the forehead, the film editing becomes confusing, with two different closeup shots of Frank immediately after the gunfire. One shot is obviously Dennis Hopper with a wide-eyed and shocked expression (as well a hole in his head) as he falls backwards. But the following split-second closeup shot is apparently not Dennis Hopper: He now has what looks like facial hair, a sullen expression, larger brow and eyes that seem almost swollen shut (and he's still falling backwards). This second cut looks like a rubber mask or very, very different makeup from that which Dennis Hopper was wearing just a fraction of a second before. The appearance is so different that I wonder if David Lynch was ever asked to explain the continuity error?
Question: Do we ever discover who the ear actually belonged to? Was it Dorothy's husband?
