Charlotte Rampling gives one of the finest performances of her career by being a cold novelist in Swimming Pool, a movie where there seems to be no clear answer to much of anything, but not in a bad way. The film is engrossing throughout, whether it’s by Rampling’s titular nature or lead actress Ludavine Sagnier’s sexy performance. A solid watch, and one that really gets you into the story, even if the premise seems like a bore.
