Teacher's Pet regularly gets shown still on Sky Movies (where I saw it), indicating that it's still a quality film.
When you think of the great romantic couplings in cinema history, Gable and Day/Day & Gable, don't exactly roll off the tongue. It's actually a threesome, here, but in a typically innocent 1950's style, along with young upstart Gig Young.
As publishing editor, Gable goes along to a class led by lecturer Day, to prove that his trade cannot be taught but learned through decades of hard graft. Of course, he falls for her but has to contend with her psychologist fiance. In the days where all this 'psych' stuff was still mumbo-jumbo, for such a cynic, well - you can picture the juicy scenes that result, where each try to out-do the other to earn Day's affections.
It is a comedy, but an intelligent one but also engaging too, with little of the heady froth that Doris Day ended up doing later (many enjoy these, I know - I don't). The script is smart and knowing and Gable in particular has an especially arched brow and raised eye, adding to the overall enjoyment. It's crisply photographed in black & white and ably directed by George Seaton.
