If I may be so bold as to give our fest a plug.... :)
The Eerie Horror Film Festival and Screenplay Competition is going into it's 3rd year and the fans, filmmakers and celebrity guests have given us the thumbs up, so I guess we're doing something right.
There's a lot of Fests out there, Shriek Fest I hear good things about as well as the New York fest.. do a Google search for "Horror"+"Film Festivals"... you'll find plenty.
Best of luck to you!
