The term FILMING SITE can be broken down into two crossword solutions: SET (3 letters) and LOT (3 letters). A filming site is a location where a movie or television show is filmed. A SET is a constructed environment, such as a stage or soundstage, that is used to create the illusion of a particular place or time. A LOT is an outdoor area, usually on a studio backlot, that is used for filming. Both sets and lots are essential components of a filming site.
