When taxi driver and working class hero Kempton Bunton (Jim Broadbent) stole Goya’s portrait of the Duke of Wellington in 1961, he became the first and only person in history to successfully rob the National Gallery in London. “I borrowed it, for the greater good,” claims Bunton, who sends handwritten ransom notes declaring he will return the painting if the government promises to shell out more money for elderly care. The late Roger Michell (Le Week-End PSIFF 2013, Notting Hill) directs this stranger-than-fiction true story of an unlikely hero and even more unlikely criminal with ample warmth and wit. Helen Mirren as Bunton’s dispirited wife Dorothy is in top form, and Fionn Whitehead (Dunkirk), as the Buntons’ son Jackie, continues his star-on-the-rise status. Funny, moving and a rollicking caper, The Duke is also a bittersweet elegy for Michell, whose reliably cozy body of work is epitomized in this irresistible swan song.
