Les Vampires is a 1915–16 French silent crime serial film written and directed by Louis Feuillade. Set in Paris, it stars Édouard Mathé, Musidora and Marcel Lévesque. The main characters are a journalist and his friend who become involved in trying to uncover and stop a bizarre underground Apache gang, known as The Vampires (who are not the mythological beings their name suggests). The serial consists of ten episodes, which vary greatly in length. Being roughly 7 hours long, it is considered one of the longest films ever made. It was produced and distributed by Feuillade's company Gaumont. Due to its stylistic similarities with Feuillade's other crime serials "Fantômas" and "Judex", the three are often considered a trilogy.
