Iris Murdoch was l’enfant terrible of the literary world in early 1950s Britain — a live wire who thumbed her nose at the conformity of the era via a voracious sex life that included male and female partners. In this snippet of her life, Murdoch (Judi Dench) faces the onset of Alzheimer’s disease alongside her adoring husband (Jim Broadbent). Kate Winslet portrays the young, free-spirited Iris in flashbacks.
