Disney - Pixar, along with other animation studios, have for the past 15 years or so, been very accurate with respect to their nonverbal illustrations on their characters. Said another way - the emotions, vocal qualities and nonverbal signals of their characters have been highly congruent - a simple principle human actors would be well-advised to heed. Yet sometimes even they are off their game.
Take for example the soon-to-be-released animated film, "Inside Out". In this movie, emotions are embodied within separate characters inside a little girl (Riley) - collectively making up her emotional psyche. The plot revolves around the turmoil created when Riley and her parents relocate from the Mid-West U.S. to San Francisco.
Here, at 0:20, the character-emotion of disgust (whose voice is played by Mindy Kaling) accurately projects her namesake while repelling from broccoli.
More accurate disgust as Kaling's character tries not to vomit (0:21)
Yet if we flashback to 0:16 we see the very classic and distinctive asymmetrical expression of contempt.
Contempt is fundamentally different from disgust, for contempt must be directed at a person or group of people - never a non-person. Disgust however can and is very often directed towards disliked food, non-living things - as well as people.
This is indeed an accurate expression and very consistent with what one expect if this were a real-world scenario. It's NOT however disgust as Mindy Kaling's psyche disgust character is supposed to be transmitting.
Riley's torso-neck-head leaning away from her broccoli and also her non-direct gaze (with rotated head) are also very congruent body language.
