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.
