Fiction Film Ideas

Introduction:
For this task, we had to brainstorm a couple of ideas for a Fiction Film Opening, it needs to last for around 2-3 minutes, I have decided to choose a couple of genres, because this would give me more of a range, I have chosen Horror, Comedy and Crime.
After I thought about theses Genres, I thought of some ideas that I know would work.

First Idea; Horror:
My first idea is based around a themed 'Zombie' photoshoot I did during the October Half Term, I plan to recreate this but as a opening scene, so it kind of links to show the story behind my pictures perhaps. The short clip will feature three of the main characters from my photoshoot, but Seth will have most of the cameratime. At the beginning, him and his girlfriend will run into a woods, he will see his friend in need of help, he will then say to Elly, 'Stay here'  he will then go to help save his friend, he succeeds and he will then turn around and realise Elly is gone, but then have to run away from the epidemic himself, I will make this look quite scary and heartracing, to make the viewers want to watch the whole thing. Half way through, he will then see his girlfriend lying on the ground, which will trigger several flashbacks of all the goodtimes they had together. He will then carry on running but eventually he will meet his end. The short film will start from the end and then continue through, if I was to make the whole thing.

The inspiration I got for this whole thing, including my photo shoot, was from several zombie films like Shaun of the Dead, Zombieland, but the biggest inspiration was from the '28 Days Later' just because it captures the point of my shoot the best and its where I got several of my shot ideas from. Although this doesn't really show in my pictures, it will show in my short piece.

Second Idea; Crime:
My final idea is crime, my basic idea of this, is it set behind garages, someone walking their dog, or just walking home from work, to make it more effective, maybe overlooking a train track, which can help set the atmosphere that something is going to happen. The person will then be confronted by a mugger, and they will exchange a few lines of dialog, an action scene will then take place and it will end with the victim laying on the floor, after being beaten up and mugged. Dramatic music will probably accompany this. I didn't really have an inspiration for this idea, but I think it came from the fact that these things do happen, and I would like to show how this can happen at anytime and anyplace.
The mugger will probably be wearing a hoody, maybe stained jeans or tracksuit bottoms, the victim, if I decide that she is going to be walking home from work, it will probably be smart/casual clothes clutching a handbag for prop use only.
