Well there is no spanking in this movie from 1939, IMDB entry: https://www.imdb.com/title/tt0031712/
But a major role was played by Ann Sheridan who received at least two spankings on camera in her career.
In this case she got spanked quite a lof off-camera by her fellow actors for not getting her line right.

She played Zelda Manion, a rascally singer who tricks a college professor (Dick Powell) into a contract with her music publisher (William B. Davidson). In one scene, after an embarrassment, she barges into the latter’s office and marches from one man to the other, slapping them alternately as she rages about what has happened:
But that tirade proved troublesome. Any scene involving slapping, whichever end it’s aimed at, is one you’d ideally want to finish in a single take; but the combination of elaborate physical action and a complicated speech proved too much for Ann. She kept mistaking her lines – which meant that, in retake after retake, her two costars found their faces getting sorer and sorer.
After a while, the director, Ray Enright, proposed an equitable way of proceeding: from then on, for every take wasted because of her flubbing, she would be spanked. In fact, each time she would get three spankings, one from Dick Powell, one from Bill Davidson and finally one from himself, Ray Enright. Ann, who was no doubt just as frustrated with herself as they were with her, consented to the arrangement, but the upshot was simply that she got spanked a lot that day. ‘It looks as if she’s welcoming spankings for slapping us,’ remarked Powell. I do wonder just a little whether the term spanking was being accurately used, or whether what she actually got was just a series of smacked bottoms, but whatever the truth, the effect was essentially the same; the press reported the incident under the headline Star Slaps So Hard She Can’t Sit Down.
And the story ended with an account of how she brought a pillow to the studio the next day, to cushion her tender seat.
