I’m not sure if Monkey Business quite counts as a screwball comedy, since there’s not really enough about money in it, and the plot lacks the relentlessness of the true screwball, in which each turn tightens the storyline.
But it is certainly an oddball comedy. It is directed by Howard Hawks, and stars Cary Grant as research chemist Dr Fulton, Ginger Rogers (in an acting role) as his wife Edwina, Charles Coburn as the boss, Mr Oxly, and Marilyn Monroe as Oxly’s not-completely-competent secretary, Miss Laurel. As Oxly says, “Anyone can type.” The screenplay is by Ben Hecht, Charles Lederer, and I. A. L. Diamond.
Fulton is working on a formula that makes people younger again, and pretty much all of the jokes in the film are variations on this. Maybe there’s something of the era in this plot, since it was made just as the idea of the “teenager” is about to transform post-war American society. As he explains to Edwina after he’s tried it out on himself:
“I took a dose of the formula and within twenty minutes I started behaving like a college boy.”
Anyway, the moment: having taken his own experimental formula, Fulton has to go out and buy a jacket and a new car. Sure, there’s a lot of back projection here, but it’s a fine sequence, with some good truck-based gags and a sense of jeopardy, and reprised shortly afterwards, with more jeopardy, as the formula wears off.
Rogers turns out to be a comedienne with good timing, as when she enquires about the lipstick that Miss Laurel has planted on her husband’s cheek during their afternoon away from the plant:
EDWINA: By the way, who’s lipstick is it?
FULTON: What’s her name’s, you know, Oxly’s secretary.
EDWINA: Oh, you mean that little pinup girl? Very cute.
FULTON: Sort of, but half infant.
EDWINA: Not the half that’s visible.
