Visible crew/equipment: A cameraman with a light coloured, short-sleeved shirt is visible (operating a large camera) when Gordon says "Interesting, got a card?" in Bud's first encounter scene. You can see him on the back wall when you look past Gekko - the wall where the door is located but closer to the main window.
Visible crew/equipment: When Natalie is talking to Bud on the phone her assistant opens the doors to Gekko's office and 3 guests follow in single file. As the camera follows them in, their shadows are displayed on the right hand door. There is another shadow moving behind the last guest, which is someone in the film crew. (00:08:50)Zim
