Heavy-handed but still poignant patriotism in this Hitchcock thriller.

It's such an entertaining film that it's almost possible to forget its didactic agenda, which is certainly part of the point.

This film contains one of Hitchcock's most famous set pieces -- an assassination in the rain -- but otherwise remains a second-rate effort, as immensely enjoyable as it is.

While Albert Bassermann earned an Oscar nomination for a somewhat hammy turn, the best performance comes from George Sanders, atypically cast as a fearless and resourceful hero rather than the cads and scoundrels he generally played.
