A Cold Rainy Night - West Virginia Productions 2013
Once a production enters into principal photography, it begins filming. Most productions are never cancelled once they reach this phase. Codenames are often used on bigger productions during filming to conceal the production's shooting locations for both privacy and safety reasons. In many cases, the director, producers, and the leading actors are often the only people with access to a full or majority of a single script. Supporting actors, background actors, and crew often never receive a full copy of a specific script to prevent leaks.
