According to a new study, what a movie character does when they step in front of a mirror may be related to whether they are male or female. If that person looks forlornly into the reflected image for a few beats before breaking down in tears, the study surmises, that person is probably a woman. If the person becomes so filled with rage at what stares back that the very mirror itself must be destroyed, then that person is probably a man. (And if that person flips open his hands and jauntily exclaims that “It’s showtime, folks!,” then that person is probably Roy Scheider playing a thinly veiled autobiographical representation of choreographer-filmmaker Bob Fosse.)
