How well can you really know your partner—even after decades of marriage? That’s the question at the heart of this emotional tour-de-force from acclaimed director Andrew Haigh (Weekend). Screen legends Charlotte Rampling and Tom Courtenay star as Kate and Geoff, a couple preparing to celebrate their 45^th wedding anniversary. But a stunning revelation—the body of Geoff’s former lover has been discovered fifty years after she fell from a mountain in the Swiss Alps—suddenly changes everything. Consumed with questions about her husband’s past, Kate reconsiders everything she’s known about her entire marriage and, as the anniversary party draws nearer, finds herself at a potentially life-changing crossroads. Boasting virtuoso, career-defining performances from Charlotte Rampling and Tom Courtenay, winners of Best Actress & Actor at the 2015 Berlinale, 45 Years is a searingly honest, emotionally stunning portrait of the mysteries that lie at the heart of every relationship. — Sundance Selects
