Okay, I admit.. The escalator actually collapsed there. I just don't want to see Lil or anyone else get hurt on those things. They are very dangerous. There have been people with their toes ripped off, lots of head and neck injuries from falling, and there is one guy who actually died when the stair beneath him collapsed and he fell into the machinery (not from a movie which has a similar scene).
Here is an official US government study about the dangers of escalators. It says there are roughly
10,000 escalator injuries per year..
