There's a fair amount of fun and humor in this entertaining spy comedy/drama. Director Dick Clement has a firm grasp on his material and with the assistance of a very ingratiating cast of players, he has presented us with a most agreeable movie. I particularly liked Norman Rossiter as a cheery villain – now that's a really grand idea which I think I'll use myself in my next Michaela Morris novel. Anyway, all the double-crossing remains credible without ever becoming merely confusing. There are also some wonderful set-pieces such as the hair-breadth escapes and the comic chase with the driving instructor. The director's use of his real locations is exemplary, the pace is fast, and the movie actually revels in atmosphere and style. At times, it's edge-of-the-seat exciting! The director also maintains a very judicious balance between comedy and drama, often using one (for example, the cheery badinage with Rossiter) to augment and deepen the other. Other pluses include a zippy music score, A-1 photography and some really fascinating locations.
