Rita Hayworth is radiant in this film--she just kept getting lovelier and lovelier. Her biographers note that she was pregnant with her first child, Rebecca Welles (Rita was married to Orson Welles at the time), during the making of this film, and maybe it's that maternal glow that makes her look even more beautiful than usual here.
Her dancing, as always, is a joy to watch, especially in the physically demanding number "You Excite Me." And her acting is terrific too. She had such a lovely soft way of speaking, very sensitive and natural, especially in the one-on-one moments with Lee Bowman (the romantic lead in the film). For a musical, it's interesting that it doesn't have the usual happy ending. The story line is more mature, more realistically reflecting the danger of London during World War II.
I highly recommend this film and sincerely hope that Columbia will bring it out on DVD very soon!
