This is almost a clone of the more-famous "Casablanca".....and almost as good! The film is very entertaining from the get-go with all three leading actors a lot of fun to watch. I am referring to Lauren Bacall, Humphrey Bogart and Walter Brennan.
This was Bacall's first film. She was 19 years old, looked 30 and never looked better. Her face, at that time, was stunningly beautiful, mesmerizing at times. So is her dialog, capped off by the famous line, asking Bogart if he knows how to whistle. It isn't just the line, it's the way she says it.....and Bogart's reaction. Bogart is outstanding, just as he was in Casablanca. Same type of character: an apolitical American overseas who reluctantly winds up helping fight the Nazis. As for Brennan, normally I don't find drunks appealing, just sloppy and obnoxious. However, Brenenan is neither here; he''s simply fun to watch and someone you can't help but like. I think he was one of the more underrated actors of his time.
The story had a good blend of intrigue, action, suspense, comedy, beautiful women, great characters and great dialog. It''s too bad it has nowhere near the notoriety of Casablanca. It 's only a small notch below it.
