It Pays to Advertise (directed by Frank Tuttle)
"When soap king Eugene Pallette kicks out son Norman Foster for planning to marry secretary Lombard, that’s the last straw—dammit, he’ll get a job! And in the soap business! Then things get sudsier amid clan conniving, business backstabbing, and romantic rhodomontade. With an appearance by silent movie siren Louise Brooks and credits listing "Carol" Lombard."
