“Les Mystères de New York” was first released in France in 1915 as a re-edited version of three chapters from the American serial “The Exploits of Elaine” (1914). The French adaptation was written by Pierre Decourcelle, a notable French writer. The series was screened weekly in theaters from December 1915 to May 1916. Concurrently, Decourcelle’s version of the story was serialized in the daily French newspapers Le Petit Provençal and Le Matin, exemplifying an early instance of a cross-promotional campaign that spanned both cinema and print media. The poster for “Les Mystères de New York,” designed by Charles Tichon, describes the work as a “roman américain” (American novel), a term used to describe a film with a dark and suspenseful atmosphere, inspired by classic American crime cinema. This innovative marketing strategy not only promoted the cinematic series but also boosted newspaper sales by attracting readers interested in following the story across different media platforms. The collaboration between film and print underscored the growing interplay between different entertainment forms in the early 20th century, paving the way for modern multimedia franchises. The poster itself remains particularly eye-catching, with its gun aimed directly at the viewer-a striking visual reminiscent of James Montgomery Flagg’s iconic propaganda work “I Want YOU” (1917).
