"French Cancan" was entirely shot on sound stages, including one big set of a Montmartre street scene, with stone steps leading up to a little square above where we find the bakery that employs Nina. (This square providentially opens onto a charming little grassy area for a romantic scene, although such a space is unimaginable in such a crowded part of the city.) A cafe on the street provides the setting for a chummy older couple who observe and comment on all the activity, and are covered with dust when Danglard's workmen detonate explosives to bring down the White Queen, a failing club which is destined to provide the land for the Moulin Rouge.
The stairs up to Nini's bakery are well-traveled by three hopeful lovers: Not only Danglard and of course Paolo, but Prince Alexandre (Giani Esposito), the unimaginably rich heir to a kingdom obscurely located somewhere in the Middle East. Fidelity is much valued by Paolo and Alexandre, but in the cases Danglard and Nini, if they can't have the one they love, they love the one they're with. These revolving romantic subplots provide Renoir with love scenes verging on farce, especially as Danglard, always with an eye out for the main chance, realizes that Nini might be useful in coaxing funds out of the Prince.
