a movie crew shut down my street for three days and i still dont know what they were filming

They put up the orange signs Monday night, so we had about 9 hours notice that nobody could park on the block till Thursday I called the city and found out the film permit was cheaper than the $75 they want from a guy with a guitar on main street. not sure how that math works out Anyway I watched for a while from my porch. a guy walked out of the same door maybe forty times one of the extras had a nice-looking analog watch on, so at least someone involved has standards. Then I saw a production assistant take it off him, which I'm guessing is a continuity thing. Somebody somewhere is going to free
