While I personally prefer Hitchcock's darker, more troubling movies, especially 'Vertigo' and 'Psycho', as far as his straightforward thrillers go 'The 39 Steps' is still one of his most entertaining. The man on the run because of false accusations or "knowing too much" motif may or may not have been invented here, but it certainly influenced dozens of subsequent thrillers, all the way up until contemporary movies like 'Enemy Of The State' and 'Minority Report'. Robert Donat makes a great hero, and Madeleine Carroll is charming and funny as his reluctant partner. The chemistry and repartee between the two is something that has been copied countless times since. Some people seem to regard 'The 39 Steps' as a practice run for Hitch's later 'North By Northwest', but I prefer the earlier movie. It may not be complex and deep, but it's great fun, and full of old fashioned movie magic. A classic thriller that is still wonderfully entertaining, and should prove to be enjoyable to almost everyone who watches it. Recommended.
