Visible crew/equipment: In the ice skating scene at the end of the movie, Shelton and others are saying good bye to Smoochy. Buggy fires, and the camera goes to Shelton falling to the ground. If you look at Shelton's head, you can see the special effects tub that shoots air (or something) out, to give the impression a bullet has just gone into Shelton's suit.
Visible crew/equipment: In the "Roxie" number, just after Roxie sings "that means somebody everyone knows" she goes down a line of mirrors and as she does you can see three crew members with what looks to be a camera in front of the middle one. Their figures are somewhat dark, so it's a bit hard to see, but it's there.
