When DiGorgio is at the steering wheel he picks up Steve and Michael, then in the exterior shots from the hood of the car, there's black material covering the passenger window at the left, and also on the windshield/car surface we see the reflection of a screen (where the camera is located).

Visible crew/equipment: 00.24.15 After Magnum has stayed up all night watching Erin's videotapes, Magnum is sitting in the chair holding the empty yogurt container then he stands up, and with this angle of the camera we see the normal ceiling. Soon after, twice we see set lighting at the ceiling, first, when Magnum tells that Erin didn't even blink, and second, when David tells Magnum that he loved Erin. (00:24:15)
Continuity mistake: While Magnum is at Erin's place he watches Erin's videotapes, and the TV set he uses changes style between wide shots and the TV's closeups, during the requisite scenes. (00:21:25)
Continuity mistake: While Magnum is at Erin's place, when he pops in the videotape of "acting class winter 1974" the VHS machine atop the TV is entirely silver on its top in this and a following closeup (also note there's black tape covering the machine's brand name). However, in other shots the machine is black and silver on top, which is even more noticeable in another closeup after Magnum shows David the videotape of Erin with the shotgun. (00:22:05 - 00:25:45)

There are three wide shots of Magnum with the two women, and a piece of equipment is visible beside the chair at the right side of the screen, which is gone in the women's semi-closeups. In the third of these wide shots, as Magnum walks toward the bedroom for the first sleeping shift, we can see crew member movement at the bottom, right corner of the screen. (00:06:55)
