Which 1929 German film made Louise Brooks internationally famous as Lulu?

The 1929 German film that made Louise Brooks internationally famous as Lulu is Pandora's Box.

Directed by Georg Wilhelm Pabst, the silent film stars Brooks as Lulu, a sexually independent woman whose relationships lead to tragedy. Its German title is Die Büchse der Pandora, and it is now regarded as a major work of Weimar-era cinema.

Brooks was an American actress and dancer who had already appeared in Hollywood films, but her performance as Lulu became her defining role. The film's lasting reputation rests on its expressive visual style, psychological intensity, and Brooks's modern screen presence.

Pandora's Box is sometimes confused with the 1929 American film The Canary Murder Case, another Brooks film from the same period. It is also distinct from the 1951 film Pandora and the Flying Dutchman, which starred Ava Gardner.
