Matthew McConaughey and Anne Hathaway were guests recently on The Graham Norton Show promoting their new film, Interstellar. In the above video of that appearance, there are several great nonverbal moments as Anne Hathaway recounts her conversation with Christopher Nolan (Director of Interstellar) - one of which is analyzed here.
The image below is taken from the 0:50 mark, where for about 1.5 seconds, McConaughey displays a sincere, yet suppressed smile.
A sincere smile must always have a relaxed (uncontracted) forehead, eyelids which are partially closed and dynamic, concave-up creases of the lower eyelids - all of which are present in this moment. Ironic to many, the mouth-component of a sincere smile can be variable. Here McConaughey displays a unilateral mouth smile component with closed lips - not a single tooth is showing (If teeth were showing, what features would have to be present for it to still be a true smile?).
