Great movie dialogue is at its funniest when you can quote a line that brings down the house but won’t mean a thing out of context. For instance, in Three Billboards Outside Ebbing, Missouri, Peter Dinklage utters these words in the middle of a dinner conversation: “Penelope said ‘begets’?” Not funny out of context, but in the movie it is preceded by certain other lines, and delivered with a certain throwaway intonation, and seen from a certain camera angle, and followed by certain reactions. It is glorious. This is because writer-director Martin McDonagh is a craftsman who places each word with wicked precision, a talent he has previously displayed in his career as a playwright, and in two films: the great In Bruges, and the rather sour Seven Psychopaths. McDonagh is so besotted with language that a large portion of the dialogue actually concerns itself with how people use words, or misuse them.
Three Billboards finds the Irish filmmaker conjuring up a fictional American town in the Midwest.
