In the new film The Woman in the Fifth (out in theaters today), Ethan Hawke starts by doing something that ought to come pretty easily by now, after two Before Sunrise movies: He makes flirty conversation with a woman in a scenic European locale. Here, it’s Kristin Scott Thomas in Paris, and the two have an unlikely chemistry … made even more unlikely by the fact that she divulges so little about her background to Hawke during their regular assignations that when he needs to call upon her to provide him with an alibi, he starts to wonder whether she really exists at all. A conundrum! But, at least in this exclusive clip, it’s an enjoyably sexy one.
