Sally Potter’s Yes is a post-9/11 love story, set chiefly in London, about a passionate adulterous affair between an Irish-American scientist (Joan Allen), who’s unhappily married to an English politician, and a somewhat younger Lebanese cook (Simon Abkarian), who’s unmarried and used to work as a surgeon in Beirut. All the dialogue, which Potter wrote, is in rhyming iambic pentameter, ten syllables to a line, apart from a few direct declarations with eight syllables. Far from a gimmick, this is the ideal way to convey Potter’s poetic intelligence and her feelings about the contemporary world. Moreover, the dialogue is delivered with such skill by the actors that it remains expressive without ever seeming mannered or show-offy.
