Once upon a time, I foolishly feared Bogart might clean his teeth with that cigarette. Now I understand that he’s employing an elaborate technique: he neatly sets the filter’s tip on his second right top tooth, then closes his lips around it. We’ll need to watch a few more cigarettes, and a few billion more frames, over another dozen lives, to test this theory with any rigor. So I’ll just choose to believe it, which is ultimately the best you can ever do.⠀
