Mine and Ellen's original idea for or main task was to show the main character walking their dog in a forest. Then for the dog to run away and the own go searching for the dog. After that the main character would find the dog but also be confronted with the beast of the forest, whom people have heard about but the people whom has seen it have not lived to tell the tale. We then decided that  this revealed too much too early on and have had to rethink our opening options. We want to make the audience  fell tension and anticipated just as Corin Hardy did.
