This is one of only three vintage West vehicles I've watched so far (three more are upcoming from the R1 set); fairly recently, I did catch the star's two embarrassing showcases made forty or so years past her prime.
The 1930s saw great development in the art of comedy, where you had remnants of the Silent slapstick style (Chaplin, Fields, Laurel & Hardy in case of the latter two, they attained new heights with the coming of Sound), the arrival of new and ground-breaking talent from the stage where the emphasis was on dialogue, puns and innuendo (The Marx Bros., West herself), the sophisticated drawing-room style spearheaded by Lubitsch, and screwball comedy (the male lead of I'M NO ANGEL, Cary Grant, who also co-starred with West in SHE DONE HIM WRONG [1933], eventually became the most representative exponent of the form).
Back to the topic at hand: West was never laugh-out-loud funny (her limited personality, bordering on narcissistic exhibitionism and reliant on an off-hand delivery of the wisecracks, is even more potentially off-putting than that of W.C. Fields hence the two's perfect teaming in MY LITTLE CHICKADEE [1940]!) but this is an excellent film in its own right. What little plot there is, is simple enough sultry carnival performer West (whose character actually shares my birthday!) turns the heads of all sorts of men. She's the girl of low-life Ralf Harolde who's jealous of her relationships with wealthy men but doesn't mind the goodies they shower her with; eventually, she herself falls for Cary Grant (who only appears halfway through the film!) and makes plans to marry him. Harolde in cahoots with Edward Arnold, the carnival boss who's about to lose his meal ticket in West's tame {sic} lion-taming act intervenes to disrupt the whole thing and, unaware of this, West takes Grant to court for breach-of-promise. Burly character actor (and later director) Gregory Ratoff plays the star's lawyer even if, in an unlikely turn of events, West is allowed to defend herself in a terrific last act; Irving Pichel (curiously enough, another occasional dabbler in directing) appears unbilled as the Prosecuting Attorney.
Uniquely for female comedy stars of the era, West (whose character is surrounded by stereotyped black maids) wrote her own scripts this one, then, includes some of her best-known lines. Still, perhaps the most outrageous moment in the film is when, overhearing a young society woman make some disparaging remark about her outside her room, West opens the door wide enough to spit at the girl (whose back is turned and uncovered!).
