The film is considered one of the most romantic of all time. Cary Grant is probably giving his best and deepest performance on screen ever. The film's theme song, "An Affair to Remember (Our Love Affair)", composed by Harry Warren and with lyrics by Leo McCarey and Harold Adamson is absolutely one of the most beautiful love songs in the world. Deborah Kerr, playing a role of a singer-turned-music teacher, is at her most beautiful and full of magic. The chemistry between Kerr and Grant is unbelievable. The film is funny, too.
