Could it be that these kids are literally being followed by adults with cameras on them at all times? Could it be that they're walking through cities where people don't drive ford f15,000s 30 mph over the speed limit?

I sure as hell wouldn't want to work with a child actor if I didn't have the parents near by for morale purposes.
That's how Vic Morrow and those two kids were killed on the set of Twilight Zone: The Movie. Working at 10pm at night with no supervision. Heck, Heather O'Rourke, that platinum blonde little girl who was the star of 'Poltergeist' died of a bizarre intestinal infection with no history of bowel problems. She was routinely left alone on the set all day with Hollywood adults who we know today sexually abused children like Corey Feldman.
There usually legally needs to be a parent or guardian that the parent has signed those responsibilities to on set in the first place
