This rather silly thriller is saved by a truly gorgeous Roger Moore, a glamorous 60's London setting and some great retro visuals - for the most part. The plot concerns agitators, international intrigue and a nest of spys that suck an ad man (Moore) and a Hungarian beauty (Claudie Lang) into the fray. The action and characters remind one of North by Northwest (1959) and the whole film comes off in hind sight as Moore's audition for James Bond.
This is a film to watch if you're fond of swinging London, the Mods, glamorous clothes and settings and you don't mind a somewhat derivative plot and extremely bad process screen sequences. There are a number of scenes that are pure comedy because of the green screen effects. Look for Bernard Lee, "M" from the Bond series, in a small role.
