Film Idea: lets see how far

the filming is mainly of self documetary or shots of the video camera, there is a note left on the camera,reading how did you get this camera and where are you, each interview of each person will be roughly between 15 - 30 seconds long,
the video will be done as if the camera has been left somewhere in london, each person tell of how they got the camera, and where they are.
people will pick up the camera on trains, buses, people will carry it and leave it in some other place.

the film wil last roughly 5 minutes in total
