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)
Visible crew/equipment: About halfway through the scene in which Bud Fox first visits his old college pal Roger, the attorney, there's a boom mike visible in the upper left-hand corner of the picture during a shot facing Roger. (00:53:05)
Visible crew/equipment: When Gekko is talking to the Airline board in the apartment, in the shot when he walks in front of the window, a boom mike is seen in its reflection.
Visible crew/equipment: Toward the end of the film, Bud is talking to Lou Manheim in the office (the thing about money - it makes you do things you don't want to do). They are both in profile, and you can see little microphones clipped behind their ties.
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.
