Visible crew/equipment: When one of the government cars drives alongside the boys on their bikes as they're nearing the bottom of the hill, in the closeup of the car the reflection of a crew member wearing a cap can be seen on the back passenger window, just as the driver speaks into his radio mic and says, "We got 'em," at the start of the shot.
Visible crew/equipment: When the two government agents pull over at the bottom of the hill one of the agents remains in the vehicle, and in the shot from inside the car just as Greg rides his bike over it, the crew member's (presumably cameraman) hand can be seen behind the agent's head in the rearview mirror's reflection. (It can't be the driver's hand since it gets blocked from view by the driver's head, within the reflection).
Visible crew/equipment: Near the start, while the agents are chasing ET, after the last closeup of the jangling keys it cuts to a shot of ET moving fast through the forest and the equipment used to help him move can be seen. This is only visible in the original 1982 unaltered version (such as on Netflix), because ET has been digitally altered in the 2002 version. Interesting to point out that the 2002 2-disc DVD set, which includes the 1982 version, has also been digitally altered in this shot.
Visible crew/equipment: After Mary and all the boys look in the shed and find tracks, when they head back to the house Tyler stops at the pizza box, and note the three distinct marks on the ground to inconspicuously signify where actors should stand while discussing the pizza. Michael stands at his curved mark, Elliott stands at his L-shape mark, and Mary's mark is in the shape of a T-mark.
Visible crew/equipment: When Elliot is luring ET with Reeces Pieces and goes into his room and through his drawers to find more candy, you can see the shadow of the crew moving on the wall next to Elliot.
