Grimm Love (original German title Rohtenburg, a pun on roh "raw" + Rotenburg) is a 2006 psychological horror film inspired by the Armin Meiwes cannibal murder case.

[1] Keri Russell plays Katie Armstrong, an American student in Germany studying criminal psychology.

She chooses a notorious subject for her thesis: the cannibal killer Oliver Hartwin (played by Thomas Kretschmann).

Oliver dreamed of eating a willing victim and, thanks to the internet, he was able to find a volunteer, a young man named Simon Grombeck (played by Thomas Huber [de]).

The film was also screened at Austin's South by Southwest festival, among others, in advance of its US release.
