In the UK they put up distinctive colored direction signs for the cast and crew to follow to get to location (e.g. https://www.google.com/search?q=filming+location+signs+uk&tbm=isch&ved=2ahUKEwi2yMmEwJz5AhV2g84BHdbDAO0Q2-cCegQIABAB&oq=filming+location+signs+uk&gs_lcp=ChJtb2JpbGUtZ3dzLXdpei1pbWcQAzIFCAAQogQyBQgAEKIEOgUIABCABDoECAAQHlCYB1jnDGCpD2gAcAB4AIABVogBpQKSAQE0mAEAoAEBwAEB&sclient=mobile-gws-wiz-img&ei=7PviYraiMvaGur4P1oeD6A4 https://www.google.com/search?q=filming+location+signs+uk&tb...) They are always cryptically labelled so that they don't attract fans etc I guess. These signs appear frequently around where I live in London. Occasionally when I am out for a run along one of my usual routes and I see a new set of signs I follow them and end up at the set. I don't make conversation or even actually stop running - I sometimes look over to try to see if there is someone famous I recognise but otherwise I'm not interested in what it is. I did a bit of background artist/extra work many years ago and know that really the process is deadly dull, but it is nice to add a bit of variety and distraction to my running route.
