Okay so I was thinking about the original "Do You Believe In Love At First Sight?" idea I had some time ago, and I thinking how I really want to make it a short movie, and how one should go about doing it; like where you should film, who should be in it, etc. Then I had this idea: what if random other people were wearing "No" shirts throughout the film? (The original just had the main character wandering around with people as per nomal.) And then: How would you get a few hundred people to wear "No" shirts for the shot? This is what I came up with:
You'll need to find a community with a semi-closed system. In other words, the people in the area should be there almost every day and will likely not travel too far out of the area. A university or school would do nicely. You'd need to print maybe 200 odd shirts and sell them to the people in this area. Hopefully with the college demographic and a plausible story about a charity or a movement, you'd sell all the shirts. Coupled with this sale is the invite to this Facebook event where everybody would wear the "No" shirt for a day. The density of "No"s would depend on your success rate.
Then you'd need to get your girlfriend's best friend to persuade her to wear the only "Yes" shirt you printed beforehand, on the day of the "No" event. (Oh, this should have come first: you need to get a girlfriend.) Then get someone with a video camera and wander around school, getting as much footage as you can while your girlfriend's best friend steers her away from you. Until the climatic end of the day when you finally meet "unexpectedly" in a moment of joy and wonder and romance with an awesome soundtrack playing in the background.
