An Affair To Remember is Leo McCarey's 1957 remake of his 1939 film Love Affair, which starred Charles Boyer and Irene Dunne an is in public domain. In general, the only remakes that I find acceptable are ones in which the director is remaking their own work and this is an almost scene-by-scene remake. But in colour and with Cary Grant.
You probably already know the story, either from watching it or from Sleepless in Seattle. Cary Grant and Deborah Kerr meet on an ocean liner but both are involved with other people. The first half of the movie is a romantic comedy with Cary Grant and Deborah Kerr falling in love amidst witty dialogue. They agree to sort their lives out and meet on the top of the Empire State Building in six months. The second half is more of a romantic drama, but with a happy ending.
I love the Grandmother.
