This is about as far removed from the Hitchcock version as you could imagine. For starters, instead of a beautiful female spy you get John Mills, (though his demise with a knife in his back in the arms of the hero in a public place might be taken as a tribute to "North by Northwest"; it's even got Hannay menaced by a plane on a lonely moor). It is, in fact, a reasonably faithful rendition of the book where Hitchcock's was a fanciful re-imagining, (and a good deal more fun), but it's no disgrace. Indeed as a Boy's Own Adventure it's thoroughly enjoyable; a Ripping Yarn in fact, with a splendid cast of British character actors, good use of locations and a spiffing climax involving Big Ben.
Robert Powell's Hannay is considerably more po-faced than Robert Donat's, (he's too stiff to be a proper action hero), and comes over as a bit of a boor. Still, you wish him well and are happy to perch close to the edge of your seat as he dodges both the police and the dastardly Huns as he attempts to clear his name. Love interest, for what it's worth, is provided by Karen Dotrice, and whose character is an amalgam of Peggy Ashcroft's and Madeline Carrol's, but this is a film in which soppy girls needn't bother us; the heroes and villains keep it ticking along nicely.
