Magazine Front Cover Research

I have started looking at film magazines which are likely to feature my horror film, so that I can begin producing my own front cover. Ideally, the magazine would be mainstream as this is the target audience I am trying to reach. When researching, I found Empire magazine to be the most popular film magazine, while Film magazine also appeared frequently. The covers of both magazines appear to be quite dark and serious, featuring a main character from a film. Whilst the dark aspect of the front covers appears to fit in with my genre, there are not many examples of horror films being featured on them. Instead, they mainly have action films such as The Avengers and James Bond. When major films come out, such as The Hobbit or Harry Potter, Empire magazine does a complete feature on them with no other films featured. This is the style of magazine front cover I want to do, so Empire magazine will be the best one of me to recreate.
