This is not a sequel to "Casablanca" but quite a different story with totally different circumstances. The main thing here is perhaps the music, since the Portuguese "Fado" culture plays an important part here. The "Fado" songs of Portugal are always overbearingly melancholy, and they are usually about love and death - one of them is a kind of figurehead to this intrinsic plot of extremely complicated machinations, since so many nations are involved in it - there are, besides the Portuguese, mainly policemen, also Germans, Poles, French, a flying Dutchman, and the main target is England, where some number are trying to get away to, one getting murdered for it. Hedy Lamarr is as shiningly beautiful as ever and steals the whole film, while Paul Henreid acts the more although in her shadow, which he is honest enough to confess himself. Peter Lorre has too small a part like Sidney Greenstreet, who always fills the screen but here not enough although well enough after his very late arrival. Max Steiner fills the background with splendid music as usual, so there is actually nothing mssiing in this muddled up espionage thriller with too many actors crowding on each other, leaving piteously small space for a romance like that in "Casablanca". Hedy Lamarr is no Ingrid Bergman, but instead she is Hedy Lamarr. This hotch-potch of late war entertainment in a duck soup of intrigue never really gets serious, but exciting enough in total suspense most of the way, although the script has some flaws, but the dialogue, cinematography and direction are magnificent. Paul Henreid's prison companion deserves some special attention and credit of sympathy, having been there for 18 years with his broom and staying there.
