Initial Idea for our thriller.

We have decided on a creepy location in which to set our opening, it is in Cheveley Park Stud at the ruins of a castle surrounded by woodland. We have decided to split out group into two actors and two cameramen. We thought it could begin with the characters walking their dog in the woods, then upon arrival at the castle grounds, the dog starts to play up and bark. This confuses and worries the two characters as their dog is normally an animal of pleasant manor. They try to figure out whats distressing the dog, so they attempt to head back. On their journey home they begin to hear noises all around e.g. sticks breaking, leaves rustling etc. The dog becomes so frightened that it runs off, forcing the two characters to follow. The dog leads them to a creepy underground well.
We will illustrate this basic plot with flashing images of the bars of the well, branches of trees, a shadow etc. to suggest this storyline so as not to reveal too much to the audience. It will start with creepy music whilst establishing the location to portray the genre of the film, it will then go to the characters playing diegetic upbeat music through hand held speakers. then as the characters start to realise their frightening dilema, the upbeat music slowly fades into the creepy music we heard at the start.
