Visible crew/equipment: In a scene not too long after Tom Cruise attempts to revive a hooker who has OD'd, he is speaking with an older gentleman. The three are in a bathroom and the hooker is passed out on a chair. One of the shower or light fixtures toward the left of the screen is shiny, and in a shot during which the camera briefly tracks in reverse, you can see the camera, cameraman and the focus puller reflected. It's pretty clear and not all that fast.
Visible crew/equipment: When Nicole opens and closes the mirror in the bathroom, you can see the camera's lens reflected on it (the camera is cover by a white thing). (00:22:34)
