In an interview with Fatally Yours:
Fatally Yours: What are your favorite horror films, books, etc.?
Barbara Stepansky: My favorite horror films are Alien, The Fog, Session 9, Creep, Near Dark and Rosemary’s Baby. I was also happily creeped out by The Others and The Orphanage. My favorite horror films of 2009 were Martyrs and Grace. One of my favorite horror books growing up was V.C. Andrews’ Flowers in the Attic – if that qualifies as horror. And my favorite comic books are Witchblade and Ascension.
