It seems not even IMDB knows how to categorize Horns, the website currently has the movie listed as a Horror, Fantasy, Drama, and Thriller. Horns stars Daniel Radcliffe and Juno Temple and is based on the novel by Joe Hill. Filmed in Vancouver, British Columbia, Canada, Horns debuted at the Toronto International Film Festival and is set to hit US and UK theatres on October 31st. Australian opening dates have yet to be announced. A full-length trailer for the film was shown at the San Diego Comic-con, check it out:
I have yet to read any of Joe Hill's work except a short story called In the Tall Grass that he co-wrote with his father, Stephen King, but this looks good. I'm pretty sure I'll be checking it out. I like Daniel Radcliffe's acting and I haven't seen him put on an American access yet, plus Horns was filmed in Vancouver, which I love, and I enjoy watching film adaptations. I will likely read the book before seeing the movie.
I definitely wouldn't call it horror or thriller. I'd say it was a fantasy comedy. It looks pretty cool. Dan Radcliffe's sounds quite different in this. Had I not been watching, and just listening, I wouldn't have realised it was him. I might go and see this.
