Review by richardchatten

Is this enjoyably unbelievable Cold War thriller for real? At least some of the humour seems intentional as the cast teams with broadly played sinister foreign caricatures (including foxy top-billed Julia Arnall) pursuing a metal that provides protection from radioactivity.

Wilfred Burns' score when not being parodically 'French' (actually Belgian) is as usual noisily intrusive. The producers actually sent sent a crew to Belgium and as photographed by veteran Geoffrey Faithfull it all looks good.

It's also nice to see Anton Diffring and Roger Delgado working for the law for a change.
