Planning for thriller

Today we were told to start planning for our thriller project, so in the beginning we began brainstorming ideas on sugar paper. We settled on an idea i came up with, it would be a romatic thriller, which was to show a young man and women walking in the park, we show having a major argument because the boy was flirting with a girl who was passing by, they then split up. We were then going to show how the break up had sent the girl over the edge and she has now become obsessed with the young man. As you can see we had planned a feature length film and not an just a 2 minute opening. so we had to shorten it drastically. We shortened it to we show the young couple waking through the shopping centre, while being followed by a mysterious young lady........then we would show this same young lady making her way to a grave yard....the key part of the whole opening would be the picking off petels from a rose, which would tie in & connotate the romantic genre we hoped to denotate ..........Also we decided on a title
Love Me..........Love me not
