Gesetze der Liebe: Aus der Mappe eines Sexualforschers (English: "Laws of Love: From the Portfolio of a Sexologist") is a 1927 film produced by Magnus Hirschfeld, a sexologist who ran the Berlin Institut für Sexualwissenschaft ("Institute for Sexual Science"), Hermann Beck and the Humboldt-Film-Gesellschaft.

[3] Like its predecessor film from 1919, Anders als die Andern[4][5] (English: "Different from the Others") – one of the first films to openly depict homosexuality – it campaigned against Paragraph 175, the provision of the German Penal Code which prohibited sex between men (sodomy law).

[3] The fifth and final chapter was an abridged version of Anders als die Andern entitled Schuldlos geächtet!

[3] During the few days it actually ran in Berlin, chapter 5 ("Innocently Outlawed") was not well received, even among the gay press.

[3] However, it is this chapter which was smuggled out of Berlin and into the Soviet Union in 1928, where it played under the title Zakony Ijubvi ("Laws of Love"), now the sole version of Anders als die Andern in circulation today (the German copies being destroyed during Nazi Germany, who saw Hirschfeld's work on homosexuality as degenerate).
