I have such lovely memories of Grace Moore in this movie which I first saw in 1968. I liked her subsequent films with Franchot Tone (The King Steps Out)Cary Grant (For You Alone) and Melvyn Douglas (I'll Take Romance) but One Night of Love is my favourite. I have a precious video copy from TV but hope Columbia will release it on DVD soon so that many more folk will perhaps share my liking for this singer who wasn't much of an actress but somehow in this film the character fitted her. And her singing is first class - her "One Fine Day" is so moving. Tullio Carminatti is very good as her singing teacher whom she falls in love with. Grace tragically died in a plane crash in 1946. Who knows, maybe Columbia will give us a box set of these 4 of her films.
