I walked past a film set in my city and I happened to be wearing mostly black and a black ball cap and I was asked where a piece of equipment was when I was just walking by.

Film crews are large, typically not one continuous unit, ie there’s always new people on set so seeing a new face isn’t uncommon. They’re also extremely busy and overworked so it doesn’t take much at all to blend in. Even if you just happen to be walking by with no intentions of trying to work your way onto a set.
