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.

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

In 2007, Russell also completed roles in Grimm Love (titled Rohtenburg for its German release), in which she played Katie Armstrong, a graduate student who writes a thesis paper on an infamous cannibal murder case, and the thriller The Girl in the Park, opposite Sigourney Weaver, Kate Bosworth and Alessandro Nivola.
