In this exquisitely calibrated film by Andrew Haigh (Weekend), Charlotte Rampling (The Night Porter) and Tom Courtenay (Billy Liar) perform a subtly off-kilter pas de deux as Kate and Geoff, an English couple who, on the eve of an anniversary celebration, find their long marriage shaken by the arrival of a letter to Geoff that unceremoniously collapses his past into their shared present. Haigh carries the tradition of British realist cinema to artful new heights in 45 Years, weaving the momentous into the mundane as the pair go about their daily lives, while the evocatively flat, wintry Norfolk landscape frames their struggle to maintain an increasingly untenable status quo. Loosely adapting a short story by David Constantine, Haigh shifts the focus from the slightly erratic Geoff to Kate, eliciting a remarkable, nuanced portrayal by Rampling of a woman's gradual metamorphosis from unflappable wife to woman undone.
