Réalisateur prolifique, il a tourné plus d'une cinquantaine de films en trente ans. Il a marqué l'histoire du cinéma par ses comédies, avec notamment Sérénade à trois, Ninotchka, Rendez-vous, Jeux dangereux (To Be or Not to Be), Le ciel peut attendre, ou encore La Huitième Femme de Barbe-Bleue.

Ernst Lubitsch (January 29, 1892 – November 30, 1947) was a German film director, producer, writer, and actor. His urbane comedies of manners gave him the reputation of being Hollywood's most elegant and sophisticated director; as his prestige grew, his films were promoted as having "the Lubitsch touch".

Lubitsch is best known for screwball comedies and romantic comedies, such as Trouble in Paradise (1932), Ninotchka (1939), The Shop Around the Corner (1940) and To Be or Not to Be (1942). While being escapist, his films often offer social commentary on human relationships and society in a satirical way.

Andrew Sarris in his influential book of film criticism The American Cinema: Directors and Directions 1929–1968 included him in the "pantheon" of the 14 greatest film directors who had worked in the United States.

Ernst Lubitsch (Berlim, 28 de janeiro de 1892 — Hollywood, 30 de novembro de 1947), foi um actor e director de cinema alemão. Os seus filmes eram engenhosos e sofisticados, com uma maliciosa sexualidade. Em todos eles há o famoso "Toque Lubitsch". Há muitas definições do que seja de facto o Toque Lubitsch, mas a maioria delas foca o seu único, nada convencional e um pouco efémero jeito de fazer filmes. Seu primeiro trabalho no cinema surgiu em 1912 como actor. Sua reputação como grande director do cinema mundial atingiu o ponto mais alto após o lançamento de Madame DuBarry (1919) e Anna Boleyn (1920).
