In any case, the movie is directed by Jodie Foster, who also performs in the film, and about whom Steven writes:
It's notoriously hard for an actor to direct his or herself on-screen, which may account for the lack of warmth in Foster's scenes with Gibson.The problem here is that, while his and hers go together like Mel Gibson and raging misogynist anti-Semite, the reflexive pronouns are, of course, himself and herself. (True, hisself is a variant in some dialects, particularly those featured in movies where Jackie Gleason plays a sheriff, but not in Standard Written English.)
So how do we solve this? Some people--those with a sense of panache and derring-do--see an opportunity here to deploy a sexy suspended hyphen, like so: "him- or herself." But if that seems too risqué, we can also go with the stodgy but serviceable "himself or herself." Or, we can simply avoid the whole pickle by recasting the sentence: "It's notoriously hard for actors to direct themselves on-screen...especially when playing opposite a volatile misogynist anti-Semite."
