Researching the Big Top

So here's some images of research I did for the next project. I kinda just want an insanely large line of people (maybe statues) or an intractable crowd that you can push/shoot your way through to get to the big top. I also want some sort of fight to start up in the ring inside the big top, but I need to get bots to work properly first.
Also, any clue on where I can learn to do cloth in UDK? I'm going to need that for this project I believe.
Here's some images:
