Woman in the Moon (German Frau im Mond) is a German science fiction silent film that premiered 15 October 1929 at the UFA-Palast am Zoo cinema in Berlin to an audience of 2,000. It is often considered to be one of the first "serious" science fiction films. It was directed by Fritz Lang, and written by his wife Thea von Harbou, based on her 1928 novel The Rocket to the Moon. It was released in the US as By Rocket to the Moon and in the UK as Girl in the Moon. The basics of rocket travel were presented to a mass audience for the first time by this film, including the use of a multi-stage rocket. The film was shot between October 1928 and June 1929 at the UFA studios in Neubabelsberg near Berlin.
