The trailer above for an unproduced Jersey Devil flick titled "Deviltry" was posted a couple days ago over at the blog Philebrity! The story goes according to Philebrity . . .
"Back in 1990, Philadelphia-based filmmaker Chris Blake Sasser filmed a trailer for a New Jersey Devil-based horror flick called Deviltry to raise funds for the low-budget production. While a full feature never materialized, the two minutes of cheesy movie magic (oh man, the acting in this is something out of a Joel Hodgson fever dream!)"
I have since watched that trailer a few times now and truly wish that this movie saw completion!
