The illusion of reality can also be stronger; on a set, it is hard to replicate real-world wear and tear, as well as architectural details, and the vastness of a city is difficult to recreate on a backlot.The failure of Camelot (1967) caused American filmmakers to shift exterior shots from studio backlots to authentic locations.The convenience store where Clerks was shot was open during the day, so the crew could only shoot at night; this necessitated the shutters on the windows be closed to hide the fact that it was dark outside.A film that becomes a blockbuster hit can introduce movie audiences around the world to a visually breathtaking location that they were previously unaware of, as the Lord of the Rings trilogy did for New Zealand.These shots can then be edited into the final film or TV program alongside studio-shot sequences, to give an authentic flavor, without the expense or trouble of a full-scale location shoot.
