Security on The Dark Knight has been pretty impressive considering how everyone and their mother wants to get a real look at that set and what’s going on there.

just witnessed the Joker’s semi being flipped over from the back to the front. It drove North on LaSalle and shortly after it crossed Monroe it did the flip. I would give it a 10 for nice form and degree of difficulty. Turns out that the spikes in the front were for the front end to dig into the pavement to help it flip. Now the truck is crushed!! Saw The Joker in full makeup hanging around in front of Northern Trust Bank. He was doing things any villan would do…high-fiving, text messaging, smoking, and actually looking bored.

Well, enough about that… here’s the video:
