Visible crew/equipment: When the car comes to a stop next to City Hall Park, there's a crowd of bystanders in the back watching the filming.
Visible crew/equipment: When Beetlejuice is first introduced, right before we see him, the camera rotates around the model and the sign above the grave lights up. Right before the sign lights up, you can ever-so-subtly see a part of the camera's shadow move over the model. It's subtle and easy to miss, but once you see it, it's pretty obvious.
Visible crew/equipment: At the rodeo, just as the tornado comes, there is a shot panning across some equipment that ends with the guy shouting into the microphone for people to evacuate. As it's panning across the equipment, it's casting shadows on it.
Visible crew/equipment: When the 6 main characters open the hatch to the sewer, there appears to be a crew member helping them open it. There is only 6 of them in the scene. But, there is a seventh person at the top who looks to be wearing a m95 mask. This is also in the opening scene of the first trailer.
