Minaccia atomica

An absorbing tale, well-told.

The big picture - London being evacuated, Prime Ministerial meetings, military operations - are contrasted with the anti-hero's attempts to evade detection among the city's ordinary people. His encounters with a seedy land-lady (brilliantly played the late Joan Hickson), and a fading second-rate actress, are depicted in fine detail.

But the film never gets bogged down - whenever the pace threatens to slow-up the scene cuts to racing police cars, thundering army convoys, or shrieking steam trains.

Carefully photographed set-pieces, solid acting all round, and a tense climax. Top stuff.
