The movie stars Ronald Colman, Celeste Holm, Vincent Price, Barbara Britton and Art Linkletter.

Beauregard and Gwenn watch a television quiz show, Masquerade for Money, hosted by Happy Hogan, and sponsored by Milady Soap.

Each contestant dresses up in a particular costume, which determines the type of questions asked, with the prize money doubling with each correct answer, starting at $5 and reaching a maximum of $160.

A contestant can quit at any time, but an incorrect response results in the loss of all money previously won.

To get even, Beauregard enters Masquerade for Money, dressed as an encyclopedia, which means the host can ask him questions on any subject.

Realizing Flame has betrayed him, Beauregard initially struggles but eventually comes up with an answer, which Happy says is incorrect.

Unaware of this, Beauregard spanks her with her hairbrush and informs her that he deliberately misled her, that he actually "spent an entire season with Einstein", but also admits that he has fallen in love with her.

Beauregard was motivated to make such a deal because two Treasury agents had signaled their intent to tax a significant amount of his winnings.

But with a chap named Art Linkletter cast as the quiz-master, we cannot fathom the basis for the sister's romance.

Laham also places Champagne for Caesar in the historical lineage of screwball comedy, over a decade after that genre had reached its peak before World War II.
