Visible crew/equipment: When Ferris and gang are driving into the city (Chicago), you hear a song being played and they show an aerial view of Chicago. When they do a flyby of one of the buildings, you can clearly see the helicopter and the cameraman that is doing the filming, in the reflection of the building's windows.
Visible crew/equipment: When Ferris picks up Sloan at school he puts her in the car and walks to the left of the screen. He then enters the Ferrari from the right of the screen. He obviously had to walk around the camera man to do this. You can also see a reflection moving back and forth on the driver's side door while this is unfolding. Presumably the cameraman's.
Visible crew/equipment: In the scenes where Sloan, Cameron and Ferris are driving to Chicago for the first time in the Ferrari, there is a brief shot of the Ferrari passing a car on a bridge. Look in the bottom right hand of the screen, a perfect shadow of a person on the road. (Original VHS version, it has been taken out of the recent TV versions).
Visible crew/equipment: After Ferris picks up Sloane from the school and they leave the parking lot, there is a shot from behind the car as they drive away and Cameron emerges from his hiding place. The following vehicle and the camera boom are visible in the reflection on the car's trunk.
