L'escalier Daru in the Louvre: Belphégor (Henri Desfontaines 1927); Funny Face (Stanley Donen 1957); Bande à part (Jean-Luc Godard 1964); The Dreamers (Bernardo Bertolucci 2003)
The escalier Daru is part of Hector Lefuel's modifications of the Louvre in the 1850s. Lefuel was the Louvre architect from 1853 until his death in 1880. The escalier Daru was only fully completed in 1930.
Straub and Huillet give two views of the Victory of Samothrace, but do not show the stairs above which the statue was placed in 1884.
L'Escalographe is an occasional blog about stairways in Paris that appear in films
My chief work of reference is François L'Henaff's magisterial Paris en marches: les escaliers des rues de Paris, published by the APUR, and available here.
