Neil Marshall is directing the movie.
According to CBS, the film is about a Halloween night of fun that turns deadly at America's premiere horror-themed park when an actual costumed serial killer begins slaying patrons who believe it's all part of the show.
CBS is hot on the project, which is hopes to start shooting this summer and turn into a franchise.
Dauberman knows his slashers: he did revisions on the most recent "Final Destination" and "Nightmare on Elm Street" movies.

And Mandate and Ghost House Pictures recently brought him on to polish "Burst," a spec he brought the companies. Meanwhile, his "Crawlspace," set up at New Line, is out to directors. New Line has targeted the movie for production this year.
"Hellfest" has solid credentials. Gale Anne Hurd, the renowned producer of "The Terminator," "The Abyss," "Armageddon" and "Hulk," among others — and who wrote "TheTerminator" — is producing through her Valhalla Entertainment.
Marshall wrote and directed the 2002 "Dog Soldier," the 2005 "TheDescent" and the 2010 "Centurion."
