Monkey Business

Mildly amusing screwball comedy about the effects of a youth formula on a married couple, in the vein of (but not as witty or funny) Hawks' 1938 Bringing Up Baby, which also starred Cary Grant.

Attempt to draw out a thin, familiar slapstick idea isn't carried off.

Monkey Business ranks with the best works of the American cinema.

...eventually becomes just as silly and over-the-top as one might've anticipated.

As soon as this gag is established and provokes the obvious guffaws, the subsequent changes rung upon it become just a little dull.
