Visible crew/equipment: The head of a crewmember is visible during the mirror room fight. During the part where Lee is slowly moving across a mirror (just before he turns down the corridor and Han comes up behind and slashes his back), look down the corridor where Bruce is about to turn down and you should see it. Also after Han slashes his back Lee turns around and goes back down the corridor and you can see this crewmember again but more.
Visible crew/equipment: Near the end of the movie, Bruce Lee knocks Han to the ground and then the shot changes to show a frontal view of Bruce. He then lands a kick to Han's head that sends Han flying across the room. As Bruce moves towards the camera you can see a pointy object on the left side of the screen that a crew member must be holding, because in the next shot there is no pointy black thing in Bruce Lee's path.
