Admirers of playwright Terence Rattigan might be thrown by the first 20 minutes of this adaptation of his 1952 work, in which the suicidal Hester (Rachel Weisz) recalls her love life in a fragmented puzzle of images to the plaintive strains of Samuel Barber's Concerto for Violin and Orchestra. After that, however, this beautifully acted relationship drama reveals its more traditional aspects, with Weisz on stunning form as the middle-class wife who drops out of a loveless but dependable marriage, only to find that life with her new, much younger lover (Tom Hiddleston) isn't really enough for her, either. Somewhat revised from the play, The Deep Blue Sea is a heady and often heartrending study of lovers at loggerheads, and fans of director Terence Davies's earlier, more autobiographical films (Distant Voices, Still Lives, The Long Day Closes) will see his sure, steady signature in its gold-burnished visions of peeling paint, wartime bomb shelters and jaunty pub singalongs.
