Suggestions for my short film.

I am starting preproduction on my third super-8 student short film and I think I have a pretty good storyline in the works for the short. I'll describe the story first so you will know exactly what I want suggestions for.

Since I'm using super-8 perfectly sync sound is out of the question. So I have created a story where the main character starts out deaf but she doesn't know why she suddenly became deaf. The only thing that will be heard in the soundtrack is some music, her heartbeat that gets quicker throughout the story and a voiceover of her thoughts.

It starts out with a girl in her early twenties breathing fast and hard. Blood trickles out of her ears and on to the floor she stands on. She looks confused and in voiceover asks herself the question "Who Am I?" She looks down at the bloody axe she is holding. Then looks at the ground where a blood soaked mutilated man lays dead. She drops the axe and faints to the hardwood floor. Fade out. Opening titles. Fade in to her lying on the floor opening her eyes. She gets up suddenly. The man who lay dead on the floor is gone. The axe is missing.

What happens next is in a lot less detail because I still need to visualize it shot for shot.
The plot for the rest of the film involves her being stalked by the man she thinks she killed. While she tries to avoid him she has flashbacks of who she was and how she came to kill this man in the first place. The flashbacks just don't happen like her remembering stuff, she actually relives these flashbacks in third person watching herself. After a flashback sequence when she come back to present day she has a close call with the axe wielding man that she killed (there will be no question that he is dead by the way he will look). Anyway the flashbacks keep on getting more real she even grabs a piece of cloth on one and it still remains in her hand after the flashback ends. She starts to try to stop herself in these flashbacks (I hate that word but is there any other way to describe them?) but finds that she can't touch the people in them.

The short ends with her watching herself getting ready to kill this guy, she is powerless to stop herself. She has no idea what to do and just starts to yell at her flashback self to stop. Her yells turn to screams as she sees her self raise the axe over this guy (he is either incapacitated at the moment or has no Idea that she is behind him getting ready to kill him). She screams as loud as she can into her Flashback self's ear but the axe still goes down and kills the guy. At that same time she notices her flashback self eardrums bursting. Her screaming at herself is what caused her to go deaf and possibly get amnesia. Before she has time to reflect on these strange turn of events her flashback ends. She turns around just in time to see bloody an axe coming down straight at her. Cut to black.

Now I have figured out most of the tricky shots in this and everything but I can't for the life of me figure out a satisfactory reason on why she wanted to kill this guy in the first place. I want them to know each other and maybe be even boyfriend and girlfriend. But I don't want some clichéd reason like he cheated on her or she did it for the insurance money. Could someone give me some suggestions please. I might not use any of them but at least I hope some will spark ideas of my own. I'd really appreciate it.

No really I can't get away with it. The film is required by the teacher to have a voiceover and other voice work. But I do intend to have it be a very minimal voiceover that is only at the begining of the short. Because I do agree that the stories that have no voice acting in them always enthrall me.

I kind of like the idea of not letting the audience know why she killed him but it really helps me to know her motivations during the preproduction.

Rath. The story will take place during the day indoors. I have a semi dark blue filter lens for my camera that I plan to use to make it seem overcast outside and also to cancel out the yellow of the lights. For the flashbacks I am going to use my yellow filter so the audience will know that is is a flashback. By the way a friend of mine did try to shoot day for night on super-8 and it came out fine. It didn't really look like night but instead had this cool twilight feel to it. I'll take your word for it on not hiring an dancer to be the actress. (what is the story behind that?) Most of my actors are film students them selfs and my main actress is a neighbor who is in highschool.

Interesting story. Tanks for the advice Rath.

Anyone else have suggestions?

Interesting but not what I'm going for. Thanks for the suggestion though.

By the way, Nelson I love that picture, Its better than any emocon currently available on the web.
