A film studio can also simply mean the specially-equipped building in which movies are shot, regardless of whether it is part of a larger all-encompassing media company. Some folks conflate production company with film studio, but as alluded to above, that’s not always the case. The reason people may perceive everything to happen under one roof could be due to the fact that major film studios (and even movie theaters) were owned by production companies during the so-called “Golden Age” of Cinema between the late 1920s and 1940s.
