Demon Keeper is a 1994 American horror film directed by Joe Tornatore for New Horizon Pictures.
The original cut of the film was felt to be not scary enough so at the behest of Roger Corman additional scenes were shot using a demon.
According to Imagi Movies "The addition is laughably obvious, for two reasons: first the demon never appears ‘on the sets where the original footage was shot; second, the new scenes were done on video tape and run through the “film-look” process, with less than good results.
"[1] The Roanoke Times called it "fun if you're on the mood for a really bad movie.
"[4] In a review for the Orlando Sentinel, Joe Bob Briggs wrote "not since Plan 9 from Outer Space have this many earnest authors been this sincerely awful.
