Visible crew/equipment: During the fight with Zhou Cheng, Danny's face is blurred during a shot, revealing it was a stunt double. (00:45:40)

Prodigal Son - S5-E3

Let the Great World Spin - S4-E2
Visible crew/equipment: Marty visits the FBI agent at her home. The camera starts far away from them in another room, and pushes in through the door frame. On the left side of the frame, the camera's shadow becomes very obvious as the shot moves.
Visible crew/equipment: When Jane straight up tells John Swift that she's taking a "vacation" so she'll be out of his hair, just as Jane walks out of her own office, the red T-mark is visible on the floor at the doorway. (00:15:45)
The System - S1-E2
Visible crew/equipment: Jim Phelps gets the disk system from the locker. He then takes a step back and looks around the room figuring out where to sit to play the recording. As the camera moves to follow, a boom mike gets in frame in the right corner. (00:03:00)
Visible crew/equipment: At the very end of the episode, as Poirot's car drives off headed to the harbor, filming equipment is neatly reflected in the door. (00:51:40)

Visible crew/equipment: When we see the first patrol car reaching the crime scene, the robbers are startled and fight the cops. But if you look in the background when the patrol car pulls over, you can see there is already at least one policeman on foot. However, he's in the background - a real-life cop stopping traffic so the scene can be filmed. (00:03:40)
Visible crew/equipment: Shadows of the boom, crew, and cameras can be seen moving about in overhead shadows during varied scenes.
Visible crew/equipment: In the final minutes, it is possible to see a drone flying between the camera's point of view and the subject being filmed, the DEA agents' van going into Mexico. Likely filming equipment, but even if recreational it's hardly appropriate for the 80's. (01:06:30)
