[1] The play was a Florenz Ziegfeld Jr. production written specifically for Marilyn Miller that opened on December 21, 1920, at the New Amsterdam Theatre on Broadway.

[2] As described in a film magazine review,[3] Sally (Moore), from a foundling asylum, is a dishwasher at a cafe resort in Paris when a refugee, the Duke of Checkergovinia (Errol), is also employed in a like humble capacity, unknown to his fellow workers.

Sally again meets Blair Farquar (Hughes), who had rescued her in an alley fight and who has had an affair with the Russian danseuse Noskerova, as had the Duke.

Otis Hooper (Murray), an American theatrical agent, sees her dance and suggests that Sally pose as a Russian dancer at a fete.

[4] During the production of this film, Moore met a young gag man who worked for Alfred Green who billed himself as a “comedy constructor,” named Mervyn LeRoy.
