This was an experiment using only three or four seconds of film. I made a gif out of it, ran it forwards and backwards, and slowed it down dramatically.
Elizabeth Holmes has always had weird, scary, sociopathic facial expressions, with everything calculated for effect. Her recent days in court saw her discarding this elaborate technique, substituting vacant, staring eyes, a ducked head, brown hair escaping a messy bun, and everything else that she might think would make her seem more sympathetic. The actual effect is disturbing: the eyes look almost like holes, and her habit of ducking her head and constant slight nodding is almost pathological. I have seldom seen anyone come across so badly in a courtroom.
The gif I used for facial analysis is from an interview in her early-ish days, when her hair was still carefully styled (longer on one side than the other) and preternaturally blonde. We see a lot of features of the Elizabeth Holmes facial repertoire, which is actually rather narrow. At first is the kind of level death-stare that often pops up as a micro-expression: people feel uneasy and don't know why, or just feel as if they are in the presence of someone/something magisterial and just a little terrifying. But prolonged, the microexpression IS terrifying, the dead-set, blank-eyed glare of a merciless, soulless predator.
Then comes the other set in the repertoire: the coy little smile with the half-moon eyes, which is on the surface of things almost charming, and certainly a manipulation of face which is calculated to charm. But the shiny blue crescents always seem a bit mad to me, glistening unnaturally. The smile is tightly restricted at first, but then comes the "pop" of very white teeth. But there's a funny thing going on here. Even vastly slowed down, the teeth show only very briefly before her lips close over them again. It's as if the smile is bitten off before it can bloom.
Elizabeth is quite tight-lipped and often purses her mouth very noticeably. Along with the pursing, however, comes an unreadable expression, with her eyes looking down. The woman who never blinks is suddenly blinking, again and again. No more hypnotic stare here - it's as if she has something to hide. Is she, after all, afraid of getting caught? Or is this just blankness, the lack of feeling or soul or anything that makes a person vulnerably human? But in the final analysis, it may just be boredom, the realization that the focus is not exclusively on her, one hundred per cent of the time.
