L'Assommoir (English: The Drinking Den) is a 1909 French drama film directed by Albert Capellani, adapting the eponymous 1879 play by William Busnach et Octave Gastineau, itself based on the 1877 novel by Emile Zola. It is the first French feature-length film and the second produced by the Société cinématographique des auteurs et gens de lettres (SCAGL) [fr] (English: Cinematographic Society of Authors and Writers).
