Plodding spy story
31 July 2016 | by (United Kingdom) – See all my reviews

CLOAK WITHOUT DAGGER is a cheapie put out by Balblair Productions, who released precisely three films during their short-lived career in the film business: this, THE BLACK RIDER, and STOCK CAR. All of them were written by prolific screenwriter A. R. Rawlinson and STOCK CAR is probably the best of the rather nondescript bunch, a gangster story set in and around a garage. CLOAK WITHOUT DAGGER is more undistinguished, a film in which the villains are spies working for their own purposes.

It starts off well with some top intrigue inside a nondescript hotel and goes downhill from there. Leslie Dwyer is a likable enough familiar face in the British B-film genre but he's miscast as a detective here. Mary Mackenzie is much better as the plucky heroine who literally stumbles over a corpse at one point. There are welcome roles for Allan Cuthbertson, Bill Nagy, and Frank Thornton, but the whole thing feels rather lifeless and drawn out, a far cry from the best of the spy thriller genre. Perhaps the budget just wasn't up to the job.
