I feel like I've seen this premise done before but Fright Fest looks like a good time regardless. Check out the trailer below! The film ironically premieres at the Fright Fest Film Festival in London.
"Blood runs rampant on Halloween night when a small towns’ Fright Fest becomes real inside the walls of a long abandoned asylum."
Directed By Ante Novakovic from a script written by Robert Gillings, Fright Fest stars Dylan Walsh, Madison McKinley, Romeo Miller, Luke Baines, Robert Scott Wilson, Johnathan Camp, Pancho Moler, Heather Ann Davis, Mercy Malick, Ashley Blankenship, Kresh Novakovic, and Michael Kupisk.
