In early Hollywood things were pretty lax until 1934 when the Hays Film Production code (film censorship) was implemented by Joseph Breen. The code feel apart in the mid 1950s and was replaced by the MPAA in the late 1960s. As a result, films before 1934 and between 1954-1968 often have darker, more adult subject matter. Anna Christie is pretty dark.
Anna Christie was Greta Garbo's first talking picture, she starred in both this (English) version and the German language version, both in 1930. Her accent is a bit jarring, especially given that Anna is supposed to be from Minnesota. It's also very early talkie, and feels like one.
Before subtitles became common place they used to shot multiple language versions of the same film for export. Most are lost but both the English and German versions of Anna Christie exist.
