The play on which the film is based,
Claude Farrère's and Lucien Népoty's ''Veille d'Armes
(also listed as Veilles d'Armes
) was adapted by Michael Morton and titled In the Night Watch'' upon its
London opening on December 21, 1918, and its New York debut on January 29, 1921. The 1921
Broadway production by the
Shubert brothers starred
Jeanne Eagels, with
Robert Warwick (playing a sixth-billed supporting character in the film) in Walter Huston's role of the husband and
Edmund Lowe in the Warren William part of the lovestruck lieutenant. It provided the plot line for a 1925
French silent directed by
Jacques de Baroncelli and distributed as
Before the Battle in the English-speaking world. An American silent version was released in 1928 under the title
Night Watch, directed by
Alexander Korda, with stars
Billie Dove and
Paul Lukas. Three years after the release of
The Woman from Monte Carlo,
another French version, directed by
Marcel L'Herbier, with stars
Annabella and
Victor Francen, was released and subsequently marketed in English-speaking countries as
Sacrifice of Honor. ==References==
