This movie is a tour-de-force of Hitchcock's skill in marshaling skilled technicians, artists, writers and actors to produce intelligent, engaging and commercially successful films, but more than that - his patriotism is on full display in this picture.Understand this combination screwball romantic comedy spy thriller in the context of pre-war Anglo-American cooperation. The final scene was far from being tacked on, as another reviewer claims - it was the climax: a plea for Americans to wake up and realize that war was imminent and their country's involvement critical to the defeat of fascism. Think Edward R. Murrow.The playing of the National Anthem at the very end made me laugh out loud. Knowing that 'God Save the King' was traditionally played to get audiences on their feet in London theatres at the end of shows, the double meaning of the gesture, both stirring and funny, was clearly anything but unintentional.

Not Rear Window, but it is a fun movie. Fully representative of the type of movies being made in those times. Reminds me of the Bull Dog Drummond or Saint movies done at those times, only better.

This was WONDERFUL... great movie!!! I didn't know it was Hitchcock.. sorry all... but it was filled with excitement every where... loved it.. this is something I would watch again.. great..!

Hitchcock's 2nd Hollywood collaboration (after 'Rebecca') introduces many elements to be seen in later Hitchcock films. His mastery of sets, camera movement and SFX staging is fully developed in this big-budget (for its time) spy-thriller. The romantic element is often the weak point in Hitchcock films, but this time the chemistry works well.Ironically, the setting for this movie was just days before the declaration of war; filming was completed just days before the declaration of war. If the final "wake-up call" scene seems tacked-on, that's because it was.

Not one of Hitchcock's better works, but it does have those wild plot twists and amazing sets and special effects for that era.

One of Hitchcocks who done it twisting turning thrillers, its all that an a bag a chips. IOf you have a passion for the black and white flixs you will love it too.
