Visible crew/equipment: In the scene at the motel where Matthew says to his mom (Erin Brockovich) "I'll bring you back some breakfast", look at the TV next to the door. You can see one of the film crew holding the boom microphone. (01:50:28)

JamesP

Visible crew/equipment: At the end of the famous court yard chase scene when Griff and gang crash through the courthouse windows, you can see in plain sight the reflection of cables and the mechanisms that held them in the air. [Corrected in 25th Anniversary edition.] (00:20:55)

JamesP

Visible crew/equipment: Just as Griff is about to crash through the front door of the court house after he is chasing Marty on the hover board, you can see someone (the director?) on some sort of crane in the reflection of the glass. (00:20:58)

JamesP

Visible crew/equipment: Right at the start, when Clark is stepping up to the front door, you can see a microphone appear down from the top of the screen. Playing this scene in real time is the best way of seeing it, but watch closely because it's only in view for about a second. (00:01:38)

JamesP

Visible crew/equipment: If you look at the money case that Doc brings with him that has all the different types of money for each year, you will see where it says 1864 the reflection on the glass or plastic of what appears to be a tripod most likely for lighting. (01:03:47)

JamesP

Visible crew/equipment: At the beginning of the movie when Clark is entering his house and the camera angle is from inside, just as he opens the door there is something red on his front porch. If you look at any of the previous scenes, that red thing isn't there. It's the bottom of a sunscreen being used to block the bright sunlight (which would have flooded the camera) behind Clark as he enters the house. (00:01:44)
