Entertaining wartime thriller from director Michael Powell. Really solid filmmaking here, Powell and screenwriter Emeric Pressburger again show their mastery of the medium. The episodic plot is uneven, and sometimes puts too much emphasis on its political messages – but there are a number of very effective suspense sequences and memorable characters from a top-notch cast (though Laurence Olivier’s accent is a bit over the top). Fascinating as a document of its time, and it still holds up as an entertaining thriller.
