The Possessed is a 2009 documentary style horror film which was released to DVD in May 2009 and had its television debut in October that same year on SyFy.

Beginning in 2006, and using the assistance of members of the Studio Nine class of Watseka Community High School, The Possessed was shot on locations in Watseka, Illinois, in the actual homes of, and including interviews of, the remaining family members of Lurancy Vennum.

Twelve years later, a Watseka girl named Lurancy Vennum began exhibiting the same behavior as had Mary.

[5][6] Dread Central wrote that the writers covered the entire story of Mary Roff and Lurancy Vellum within their documentary, with their having traveled to Illinois to interview topic experts, historians, and surviving family members.

The reviewer wrote "I was fascinated by the documentary" but stated that the latter day claimants to being possessed did not seem believable.
