Henry Cavill as Superman along with Ben Affleck as Batman - are both shown in this brief trailer-teaser. The Batman v Superman: Dawn of Justice trailer shows Superman entering a prison of sorts where along with others, Batman is chained.
The expression on Cavill-Superman's face is characteristic of two primary and often overlapping emotions.
In this moment there is a mixture of roughly 60% anger and 40% disgust. Of course these are qualitative estimates.
In this moment a few seconds later, Cavill-Superman is displaying approximately 70% disgust and 30% anger.
While Cavill is certainly not Superman, making this expression can truly engender the very human feeling of disgust, where a moment before it was only an actor's intention.
Human beings commit many acts of violence when they are reactionary and angry - for moments, hours and days. Both disgust and contempt also tend to be relatively short-lived. Yet when violent behavior and maliciousness are perpetrated over longer time periods (e.g., months, years, etc.), there is almost always a primary emotional driver of CHRONIC disgust and/or contempt - while anger takes on a smaller role.
