A gruesome real-life story about Australian cannibal killer Katherine Knight, who decapitated and cooked her partner's head with vegetables and gravy before trying to serve it to his three children for dinner, will be made into a movie. The film is expected to be released by the end of 2017 or early 2018.

In 2000, Katherine Knight made headlines when police discovered that her partner John Price was stabbed 37 times and his flayed body and skin left hanging from a meat hook. On entering the kitchen they also found Price's head floating in a pot with cabbage and zucchini. Bloodstains on the floor revealed to investigators that Price had briefly been successful in escaping the house.

The film will be based on journalist and author Peter Lalor's book titled Blood Stain that details Knight's crime. Hollywood production company Shoreline Entertainment will be collaborating with Australian producer Dane Millerd and screenwriter Ross Murray. Moreover, the film will mostly follow the facts of the incident with only a few changes.

"It's one of those stories that lends itself to being told on film," Millerd was quoted as saying by The Guardian. "Even if you can't handle the subject matter, people will still feel compelled to look."

"It took me the best part of 10 years to get the rights and once I got that, the conditions came along, which is what we're working through now," Millerd said. "One misconception is that this is going to be straight-out horror and this couldn't be further from the truth."

"We all know how it ends and I don't think it needs to be diluted by an overreliance on gratuitous violence.

"We're hoping some of, or a percentage of, the proceeds will go to domestic violence victims, both male — because of what happened to John Price — and female, because one woman a week is unfortunately killed by an abusive partner," he said.

Knight was sent to prison for life, without hope of parole, the first Australian woman to earn such a punishment, for the brutal murder
