I'd never seen or even heard of this offering in the 60's comedy spy genre until Film 4 padded out their evening schedule with it. How dated it all looked, understandably. But it was a jolly romp, great locations and with pretty good enthusiastically staged stunts. Ms Welch was very decorative as usual and the Britsh character actors excellent in support. Good to see Tom Adams in a solid supporting role, Clive Revill was always good value in this sort of movie too. Amazingly the two aircraft flown in this movie, a Cessna 172 and a Piper Cherokee 180, are still active and licenced in the UK, wearing their original registrations, forty years after the film was made.
