The ultimate tearjerker, this 1942 romance classic directed by Mervyn LeRoy (based on a novel by James Hilton) stars Ronald Colman as a British army officer suffering from amnesia after World War I. After falling in love with and marrying a dance-hall singer (Greer Garson), Colman's happy character begins a career as a writer and doesn't seem to mind that he doesn't remember who he is. A car accident changes all that, however, causing the hero's memory to return and making him forget all about his lovely cottage and bride. LeRoy modulates the obvious suspense element in the story (for example, is Colman going to remember Greer or not?) extremely well, building ever-so-deliciously slowly toward a huge payoff. This is one of the great date movies of all time. --Tom Keogh
