This is mainly going to be remembered as Glenda Jackson's last movie, and what a glorious swansong it is. Her ancient, heavily lined face - far removed from the face of Elizabeth the First, the role that sealed her stardom in 1971 - conveys shades of emotion that not all actresses can hint at. She's playing Irene Jordan, the wife of Bernard (Michael Caine) who has gone AWOL from the care home in which they live, taking himself off to Normandy to attend the 70th anniversary commemoration of the D-Day landings.

This is another of those small movies with a big heart. Nothing very dramatic happens (apart from brief flashbacks to D-Day which Bernard's best pal did not survive). John Standing has a nice supporting role as another veteran who takes Bernard under his wing; there was a hint of camp in Standing's performance, which made me think an LGBT 'attitude' moment could and should have been shoe-horned in.

Michael Caine has weathered the years better than Jackson (or he's had some work done, which Glenda very clearly has not). His performance is not quite as subtle as hers, but this is a beguiling and totally believable reconstruction of an episode which made the papers back in 2014. A couple who have loved each other for seventy years are two people you have to take your heart.

RIP Glenda, one of the finest actresses Britain ever produced. And Happy Retirement to Sir Michael, who has given us a great deal of pleasure in a long and splendidly wide-ranging screen career.
