Research into similar products - types of films posters

Similar products to my film are Friday the 13th and Nightmare on elm street as they both contain big ironic characters that strike fear into the audience e.g. Jason X and Freddy krueger. They are also similar as they involve a group of friends who slowly get killed one by one.
Throughout my film trailer there will be a big iconic figure which will strike fear into my audience similar to these two characters.
