COLOGNE, Germany (Hollywood Reporter) – A German cannibal is taking legal action to stop the release of the horror film “Butterfly: A Grimm Love Story,” which he claims is based on his life.

Keri Russell (“Felicity”) stars as a graduate student researching imprisoned cannibal Simon Grobeck (Thomas Kretschmann). Russell is drawn into Grobeck’s world and becomes obsessed with the Internet cannibal community. “Butterfly” is scheduled for a March 9 release in Germany.

But not if Armin Meiwes, who was sentenced to eight-and-a-half years in prison for eating a man he met over the Internet, has his way. In a statement Monday, Meiwes’s lawyer, Harald Ermel, said the film is a “slavish re-enactment” of the real-life events and his client did not give permission to producer Atlantic Streamline to fictionalize his story.

“I feel used,” said Meiwes, who filmed the killing and confessed to the crime but denied it was murder since his victim volunteered to be eaten.
