Bearing a title which includes the in-word of the time "spy", but otherwise no other relation to the plot, to this fan of "The Man From U.N.C.L.E." this was rather thin fare and escaped my brain almost the minute it entered it.

Unlike others in these spliced-for-European-cinema features, this effort has very few redeeming features. There are few action set-pieces, no race-against-time death-trap from which to escape, no Mr Big" megalomaniac villain to tilt our heroes against and barely even a big-name celebrity cameo to divert the viewer's attention (unless you count Vera Miles, probably the biggest name in the cast here).

David McCallum in particular gets almost nothing to do, chasing cats around "London", Robert Vaughn as ever, gets amongst the ladies but hardly memorably as the chase is on for a youth-regeneration invention. Even Mr Waverley's stepping out to join Solo in escaping from the bottom of a wine vat (unoriginally used twice for the same purpose) barely registers its novelty value.

Somewhere in the cast you'll catch sight of Yvonne "Batgirl" Craig, James "Scottie" from "Star Trek" Doohan, but otherwise this adventure has potboiler written all over it and the awful soundtrack which plays variations from "Rule Britannia" throughout to attempt to fool us that we're all in Swinging England doesn't help either.

When a scientist who has Perfected a method of rejuvenation disappears, agents Solo and Kuryakin are assigned to trace him. But their adversaries from THRUSH are determined to gain the scientist's secret.... The action-packed espionage adventures of the U. N. C. L. E. Duo take them to Paris, London and a country estate in Surrey.

All of the Man from UNCLE feature films are cracking entertainment, and One of our spies are missing is no different, however it can be a bit confusing with too many villains, some things don't make sense, and it does drag a bit. Still it's good fun with that killer soundtrack- Robert Vaughn and David McCallum are their cool selves as the charismatic heroes - the cute little cats almost steal the scene though!! So does Vera Miles as the villainess.

"One Of Our Spies Is Missing" (the title has very little to do with the content, by the way) is synthesized from a two-parter episode of "The Man From U.N.C.L.E", so you would think it would have enough coherence for a feature-length film, but it doesn't. The first half of this film makes it look like Solo and Kuryakin will have to battle one group of villains, then in the second half those are put aside to make room for a second group of villains; the problem with this strategy is that the most promising elements of the first half (like the lethal henchwomen Olga and Do Do) are underutilized. But there are still some memorable moments here, like Illya's fight with a man twice his size, or one reverse-aging image that pushes the film even further into sci-fi territory than before. ** out of 4.
