Early on back in December 08 when Yes Virginia was perhaps going to be much smaller i set to work on the film by myself. One thing that i knew would be problematic would be to get the city streets to have the right density of extras for a busy city. So i made a quick hack-job of a crowd generator in my 3d software that actually became quite powerful. It meant i could have several character variations. Also all the crowd 'clones' of those variations would use the one 32 frame walk cycle but each use of that walk cycle would be randomly offset to give the impression that each clone was unique. The opening shot on this mood film has over 150 clones walking down the left hand side of the street. I dont have collision detection or anything like that but felt it did the job for wide shots. Music here is Wilco.
