The 39 Steps

From Tysto commentaries:

Alfred Hitchcock presents his first big hit with all the trimmings: the innocent man taking it on the lam, the tough and beautiful blond sparring with him, the quirky humor, and the weird conclusion. Listen as I compare the film to Young and Innocent and North by Northwest, talk about Hitchcock’s early work and developing style, joke about the Scottish stereotypes, and stumble over British currency. Plus, you learn what a “crofter” is. Please note, however, that you will not learn what causes pip in poultry or how old Mae West is. Who am I? Mr. Memory?

There’s a great economy of story-telling in this movie, and it actually sometimes is too economical. [laughs] It’s a little miserly story-telling. — Tysto Commentaries,

I talked over the joke of the— ‘Is this your daughter?’ ‘No. It’s my wife.’ [laughs] … All right, we’ve set up a … secondary conflict in the film: Hannay versus the crofter. — Tysto Commentaries,

There we get the line: ‘Why don’t you take off your clothes? I don’t want you to catch pneumonia.’ [as Pamela] Nnnnnn— I don’t want to catch pregnancy. — Tysto Commentaries,
